(the outputed data format not matter much, if it's easier return dict go ahead) you can use groupby from itertools import groupby [(a, len(list(b))) a, b in groupby(lst)] result: [(1, 4), (0, 2), (1, 1), (0, 4), (1, 3), (0, 2)] group group consecutive elements of same value , len(list(...)) can take length of group. 1 advantage of method, it'll run in linear time.
