[Solved] Python create list combination

by

You haven’t specified in what order the keys of the dictionary should be processed in the output. If one assumes reverse sorting order, you can do this trivially with itertools.product(): from itertools import product combinations = product(*([‘{0}{1}’.format(v, i) for i in range(dictElement[v])] for v in sorted(dictElement, reverse=True)) Demo: >>> from itertools import product >>> dictElement … Read more
