How to find the different indexes of the same value?

Question

For example I have:

l = [4, 1 ,3, 4, 7 , 4]

if I use

l.index(4)

it returns back 0

How do I get it to return back 0, 3, 5?

Try this:

l = [4, 1 ,3, 4, 7 , 4]
index = [i for i, x in enumerate(l) if x == 4]
print(index)

[x[0] for x in enumerate(l) if x[1] == 4]
