Please let me know where is it going wrong. Following is a piece of codes I wrote to generate all combinations and permutations of a set of symbols, e.g. The for loops range from 0-2 which are basically the indexes of the three elements in the list. Counter method of collections library can also be ideal for this task. play_arrow.
