python 3x how to compare two lists containing dictionaries where order doesnt matter
pif the elements in both lists are shallow the idea of sorting them and then comparing with equality can work the problem with alexs solution is that he is only using id but if instead of id one uses a function that will sort dictionaries properly things shuld just workp precodedef sortkeyelement if isinstanceelement dict element sortedelementitems return reprelement sortedtesta keysortkey sortedtestb keysotrkey codepre pi use an codereprcode to wrap the key because it will cast all elements to string before comparison which will avoid typerror if different elements are of unorderable types which would almost certainly happen if you are using python 3xp pjust to be clear if your dictionaries and lists have nested dictionaries themselves you should use the answer by mcallens if your inner lists are also unorderd you can fix this to work jsut sorting them inside the key function as wellp
