I have a list:
a = [32, 37, 28, 30, 37, 25, 27, 24, 35, 55, 23, 31, 55, 21, 40, 18, 50,
35, 41, 49, 37, 19, 40, 41, 31]
The maximum value is 55, which appears twice in the data.
How can I get all indices where the maximum value appears?
>>> m = max(a)
>>> [i for i, j in enumerate(a) if j == m]
[9, 12]
