There were also other issues with integrating PyInstaller and JS\/HTML\/CSS, where you have to use Eel to communicate between the documents, and subsequently, every desktop\/web application you make will have to involve google chrome.\nSOLUTION:\nAs an alternative to building the desktop application via PyInstaller, I am building it using Blazor\/Electron. There is no direct link between Blazor\/Electron and Python, as Blazor relies on C#, JS\/HTMLCS. Therefore, I ported in IronPython into my C# file, this allows me to communicate along the following path. C# -> Python -> C# -> JS\/HTML\/CSS. An additional advantage to Blazor\/Electron is that the application can be built as a local desktop application without internet connection, and it boots up much faster. Lastly, C# allows for building Splash Screens (loading screen while the app boots up for the first time) for your application, so even if you're app is huge and it has a long load time, the user can be informed that the desktop app is loading!","Q_Score":0,"Tags":"javascript,python,html,python-3.x,pyinstaller","A_Id":63315595,"CreationDate":"2020-08-07T02:11:00.000","Title":"Why does Pyinstaller exe open and close then open again?","Data Science and Machine Learning":0,"Database and SQL":0,"GUI and Desktop Applications":1,"Networking and APIs":0,"Other":0,"Python Basics and Environment":0,"System Administration and DevOps":1,"Web Development":0},{"Question":"Is there a way to find out what width a Label would be for a given text and font, without having to add it to the graphical elements currently being displayed.\nI need to get the information without any effect on the GUI, however momentary that effect may be.

If remote browsers are not available on Unix, the controlling process will launch a new browser and wait.\nThe script webbrowser can be used as a command-line interface for the module. It accepts a URL as the argument. It accepts the following optional parameters: -n opens the URL in a new browser window, if possible; -t opens the URL in a new browser page (\u201ctab\u201d).

Of course there are other types too, e.g. when working out display metrics such as the pixel density Kivy uses a different method on each platform but doesn't expose any of that detail to the user.\nOf course things are much more nuanced when considering things as a whole. For instance, Kivy uses SDL2 as a library for creating a window, setting its size\/pos handling pause\/resume etc., so Kivy's code is of the second type here as it calls SDL2 in the same way on every platform.

Barriers to making something like this work\n\nPyBind style bindings won't work with CUDA device functions\nWhile CUDA supports passing of C++ lambda functions to kernels, it is a static compiler generated support. There is no way I am aware of to get a lambda function into a kernel call without compiler invocation (and probably nvcc and not nvrtc, which would imply a lot of messing around with compilers at runtime, or hacking extensions to PyCUDA). All of that would violate your \"cannot go into the C++ or CUDA code\" criteria.\nSimilarly, you would require CUDA runtime linking support in your application. I'm also pretty certain that the linker can't link naked lambda functions, only device functions with a generic interface (nvstd::function), so you would need to emit kernels, wrappers, and CUDA C++ device lambdas, compile them, and link them. That requires the CUDA driver API which I am sure you are not using.\n\nThe best hope you have would be to try Numba, which allows runtime compiling of Python device functions. However it lacks any ability to deal with lambda functions and can't interact with C++ code statically or JIT compiled with the CUDA toolchain. You might be forced to reimplement a lot of your CUDA C++ code in Python to make that work, and the Numba kernel dialect lacks a lot of modern CUDA features, which might make that extremely difficult depending on how sophisticated your existing CUDA code is.","Q_Score":0,"Tags":"python,c++,lambda,cuda","A_Id":64530815,"CreationDate":"2020-10-26T02:03:00.000","Title":"Best way to pass a lambda to a CUDA kernel from python code","Data Science and Machine Learning":0,"Database and SQL":0,"GUI and Desktop Applications":1,"Networking and APIs":0,"Other":0,"Python Basics and Environment":0,"System Administration and DevOps":0,"Web Development":0},{"Question":"I have a game written in Pygame and was trying to debug it.

The best way depends more on how you want to structure your app than anything else.\n\nI wonder how to assign to each black tile on my board.png its own coordinate\n\nSet the pos attribute of a widget to control its position, or better in this case use a layout that does what you want. For instance, adding your squares to a GridLayout with the right number of columns will have the right effect without you needing to worry more about positioning them.\n\nShould I create 32 transparent widgets placed on black tiles of board.png or it is impossible?\n\nI don't understand what you're asking here. You can make transparent widgets if you want but I don't know why you'd want to.\n\nAnd what widget to use for 24 checkers?\n\nThe real question is, what do you want the widget to do? e.g. if you want it to display an image then inherit from Image.\nOverall this answer is very generic because your question is very generic.

Sometimes it downloads versions I'm not using\n\nThis isn't a strange problem, it's just how python-for-android works. It needs to install packages for the android environment, which isn't necessarily possible using what you have locally, and even if it was it's still a simpler way for python-for-android to operate.\n\nMy Question is this: How can I override (maybe in my Buildozer Spec file) P4A downloading packages (I guess it's called recipes) and to JUST USE the packages I already have downloaded and installed in my Conda Environment\n\nYou can't. There are options in the buildozer.spec file to specify the source directory for a given recipe, but this needs to be pointed at the source directory of the project (i.e. for a python module the root directory with a setup.py), not the installed package in another python environment.\nDepending on how conda caches packages, you might be able to point it at what it's pulled, but this won't work for e.g. wheels.\n\nthis way my compiled APK will be exactly identical to the Kivy App I'm running on my Linux machine.\n\nIf this is your goal, you can specify versions for things using requirements=package==version, e.g. requirements=colorama==0.4.4. However, for packages installed using recipes not all versions may be supported, it's normally a good idea to use the defaults.

That also means that you have to filter the received events that are not of those types because, in MIDI, a stream of events is subject to contain many kinds of other events mixed with the notes (pitch bend, controllers, program change, and so on).\nFinally notice that MIDI doesn't produce any sound by itself.

Instead, hash them and store the hashes, then when your users try to log in, you hash the passwords they give and check that it matches the hash you have stored for them.\nSecond, your app should be running under a service account and whatever secrets it needs should be accessible only to that account, which prevents any other user from being able to read its sensitive data. For added protection, you can disable ssh and shell access for that service account, and also disable sudo and root logins on your server to make it a bit harder for an attacker to become the service account (be aware it doesn't make it impossible, just harder).\nThird, you shouldn't be rolling your own secrets manager anyway. But assuming this is some sort of toy app or school project where you're doing it to learn how to do it, keep some basic rules of info sec in mind. You can also encrypt the file you keep the password hashes in, but don't think that necessarily buys more security as anyone who can get access to your service account to read the password file at all can also get the encryption key. This is the basic reason \/etc\/passwd and \/etc\/shadow aren't encrypted and are instead protected by restrictive file permissions.\nMind you, a user database in a flat text file isn't particularly scalable, so while it works fine for servers, apps with a lot of accounts tend to use real databases, and you can use the database manager's built-in access control and encryption functionality to restrict access to sensitive tables and encrypt sensitive columns.","Q_Score":1,"Tags":"python,python-3.x,tkinter,text,notepad++","A_Id":65530461,"CreationDate":"2021-01-01T10:57:00.000","Title":"Suggestions regarding accessiblity of files in python","Data Science and Machine Learning":0,"Database and SQL":0,"GUI and Desktop Applications":1,"Networking and APIs":0,"Other":0,"Python Basics and Environment":1,"System Administration and DevOps":0,"Web Development":0},{"Question":"I am trying to build an iOS application using Kivy, is it possible to pack this application using  Windows machine?","AnswerCount":2,"Available Count":1,"Score":0.0,"is_accepted":false,"ViewCount":886,"Q_Id":65600039,"Users Score":0,"Answer":"I'm afraid not.

From a practical standpoint, there are as many rows and columns as there are pixels in the window.\nIn reality, the number of rows and columns is entirely up to you. A widget can have a single row and column or it can have several. It all depends on what you add to the window.\nA frame starts out with nothing in it, so there are no rows and columns, just empty space.

I'm not trying to determine IF there's a UAC prompt (I've got a couple of reliably ways to do that, win32gui,GetForegroundWindow() returns a 0, or win32gui.screenshot returns exception OSError at least in my case)\nI'm also not looking to BYPASS the UAC, at least from python, I have an update process that's kicking off automatically that I need to get through the UAC. I don't have control of the update process so I don't think it's a good candidate for disabling the UAC with Python. I could just disable the UAC in Win10, but I'd prefer not to if possible. I do have a couple of methods for bypassing the UAC, in one instance where I'm running this in vitualbox I believe I can use VBoxManage guestcontrol to sent keystrokes to the guest system, for a stand alone system I have a microcontroller connected as a USB HID Keyboard, with a basic deadman switch (using the scroll lock to pass data between the python and the microcontroller acting as the HID keyboard) if it doesn't get the signal it sends left arrow enter to bypass the UAC.\nWhat I'm trying to do, and getting stymied with, is verifying that the UAC popup is actually from the update process that I want to accept the UAC prompt for, and not some other random, possibly nefarious application trying to elevate privileges. I can use the tasklist to verify the UAC is up, but I'm not seeing any way to see WHAT caused the UAC prompt. The update process is kicked off from an application that's always running, so I can't check to see if the process itself it running, because it's running under normal operation, I just want to accept the UAC when it's attempting to elevate privileges to update. I've been using a combination of using win32gui.GetWindowText and win32gui.EnumWindows to look for specific window titles, and for differentiating between windows with the same title, taking a screenshot and using OpenCV to match different object that appear in the windows. Both of those methods fail though when UAC is up, which is why I can use them to detect UAC as I mentioned before.\nI suppose I could use a USB camera to take a screenshot of the system, but I'd like to be able to run this headless.\nAnybody have an idea on a way to accomplish this, as the tree said to the lumberjack, I'm stumped.","AnswerCount":1,"Available Count":1,"Score":1.2,"is_accepted":true,"ViewCount":91,"Q_Id":67415047,"Users Score":0,"Answer":"If you run a process as administrator, no user account control prompt will appear.\nYou could manually run your process as administrator.\nYou need system privileges to interact with a user account control prompt.","Q_Score":0,"Tags":"python,windows,uac","A_Id":67415235,"CreationDate":"2021-05-06T09:07:00.000","Title":"How can I determine what what is in the Win10 UAC prompt in Python?","Data Science and Machine Learning":0,"Database and SQL":0,"GUI and Desktop Applications":1,"Networking and APIs":0,"Other":0,"Python Basics and Environment":0,"System Administration and DevOps":1,"Web Development":0},{"Question":"Hello wxWidgets and wxPython people,  I want to build wxWidgets and wxPython on cygwin, but use windows widgets ( --with-msw ) so as to not require X.

Better hardware - faster. Better threading for the script - faster.

Sending information between components at a very rapid pace could cause a bottleneck. So if your script waits for that bottleneck to pass before it continues cycling passwords - it gets slowed down.

Hence, whenever you start pygame it needs to start up quite a few things in the background. Since this can be unnecessary at times pygame gives you control over it.\nFor a beginner, this might not be terribly obvious but you don't necessarily have to call pygame.init() and you could instead initiate the modules you want individually. For example, if you wanted to only initialise the font module you would replace pygame.init() with pygame.font.init(). You don't see this often in tutorials because most pygame ones are for beginners and pygame.init() is used to keep things simple.\nI guess 2 examples to illustrate why this can be useful:\nExample 1 - You want to display data with pygame and don't need text or sound\nExample 2 - You have pygame code over multiple files, let's say a file with the main code and another file with the sprite of the main character.

I'm confused as to the behavior of memory management of strings and other pointers when working with ctypes.\nThere are, to my knowledge, 3 cases I need to solve, basically:\nA) Creating memory in C and returning a c_char_p as the result of the function to the Python.\nB) Creating a string in the Python, and passing it as a char const* parameter of a C function, and not freeing it in the C: this is the only one I've solved confidently: I can just do my_str.encode(\"utf-8\") into a c_char_p, and the Python Alloc\/GC handles both the allocation and deallocation.\nC) Creating memory in Python, and storing it in the C (for example as a char* field within a struct), to be deallocated later (with a function from the C library).\nMy questions:\nA)\n\nis the c_char_p thus created a second pointer ? If so, what happens to the pointer allocated by the C ?\nhow do we free the pointer returned from the C ?\nis there a difference of behavior between how c_void_p and c_char_p are handled as restype by the GC ?\n\nC)\n\nWhat is the correct way to \"give ownership\" of a memory pointer allocated in Python to the C ? .encode() clearly makes a Python object that's GC'ed.\nis a string created by create_string_buffer also Python-GC'ed ?","AnswerCount":2,"Available Count":1,"Score":0.0,"is_accepted":false,"ViewCount":205,"Q_Id":69419126,"Users Score":0,"Answer":"This is an adaptation of the exchange I had on the Python discord server with someone who answered the questions:\n\nis the c_char_p thus created a second pointer ? If so, what happens to the pointer allocated by the C ?\n\nYes, it is. The c_char_p is a PyObject* pointer that lives on the heap, and it stores the original C char* pointer inside it.\n\nhow do we free the pointer returned from the C ?\n\nPass the c_char_p to free() using ctypes\n\nis there a difference of behavior between how c_void_p and c_char_p are handled as restype by the GC ?\n\nNo, in both cases, when the c_void_p or c_char_p is garbage collected, it does nothing, ie, it does not free the original C object that was pointed to.\n\nWhat is the correct way to \"give ownership\" of a memory pointer allocated in Python to the C ?\n\nThat's not normally something you'd do - memory created by Python is usually freed by Python, memory created by C is usually freed by C. If you need to pass something from one domain to the other, it's best to copy it. It's possible to make the C side keep a Python reference to the Python object by using the Python C API, but that's probably not the best idea.\n\nis a string created by create_string_buffer also Python-GC'ed ?\n\nIn this case, when the Python object is GC'd, it also frees the C memory. A c_char_p knows whether it owns the memory that it points to or doesn't, and when it's GC'd it frees the C memory if it owns it.\n========\nSince my (I = asker) goal is to have as few (no) reference to ctypes types for the Python end-user, given the answers above, I would do the following:\n\nwhen I malloc a char* in the C in a function char* do_c_func(), I return it as a c_char_p restype in Python. In my Python, I have a wrapper function do_py_func() that calls do_c_func(), receives this c_char_p called my_c_char_p, and stores its contents in a Python string, through some sort of s = str(my_c_char_p). I then call ctypes.free(my_c_char_p): this frees the malloced char*, and the end of the function decrementing the last reference counter, this eventually garbage collects my_c_char_p.\n\nI create a conversion function python_str_to_c_str(py_str) which takes a normal python string, and returns stdc.strdup(py_str.encode('utf-8')) (with stdc.strdup.restype = c_char_p), thereby providing a new char* to the C (which Python will recognize as having been created in the C). I use this conversion function anywhere I need to pass a string from the Python to the C. This makes it so the buffer created by my_string.encode('utf-8')), and the c_char_p returned by stdc.strdup, are both garbage-collected by the Python, but the char* itself is not.","Q_Score":0,"Tags":"python,c,memory-management,memory-leaks,ctypes","A_Id":69419127,"CreationDate":"2021-10-02T18:25:00.000","Title":"Memory management and removal of leaks, in C and Python with ctypes, using the example of strings","Data Science and Machine Learning":0,"Database and SQL":0,"GUI and Desktop Applications":1,"Networking and APIs":0,"Other":0,"Python Basics and Environment":1,"System Administration and DevOps":0,"Web Development":0},{"Question":"How do you hide the turtle while drawing in Python 3.

There are two networks at play: your internal network (LAN) and your internet (WAN). Your modem\/router connects these two networks together.

All classes have a toString() function. In general, conversions from one class to another in Kotlin are always done by calling a function on that class instance that starts with the word .to.\nThe reason Integer.toString() exists is that if you're targeting the JVM, then all the Java standard library is available as well. Java has the concept of \"primitives\" which are not classes so they don't have functions, and so it provides Integer.toString() to be able to convert a primitive integer into a String.\nJava has primitive wrapper classes that you pretty much should never touch in Kotlin:\n\njava.lang.Integer\njava.lang.Long\njava.lang.Float\n\netc.","Q_Score":2,"Tags":"python,kotlin,types","A_Id":76134311,"CreationDate":"2023-04-29T02:12:00.000","Title":"Type conversions inconsistent in Kotlin","Data Science and Machine Learning":0,"Database and SQL":0,"GUI and Desktop Applications":1,"Networking and APIs":0,"Other":0,"Python Basics and Environment":1,"System Administration and DevOps":0,"Web Development":0},{"Question":"I am writing a calculator interface in Python using Tkinter.
