How to find the max number(s) in a list with tied numbers

by

You can determine the maxval with max:

maxval = max(my_list)

Then get the indices using enumerate and a list comprehension:

indices = [index for index, val in enumerate(my_list) if val == maxval]

For your example, I get 

maxval == 58
indices = [5, 10, 11]

As per Keyser’s suggestion, you could save iterating over the list twice (once to determine maxval, once to find matching indexes) by doing:

maxval = None
for index, val in enumerate(my_list):
    if maxval is None or val > maxval:
        indices = [index]
        maxval = val
    elif val == maxval:
        indices.append(index)
