why does this function return non negative numbers?

Question

In [20]: def relu(x): 
    ...:     return (x>0) * x 
    ...:

Is that because in Python, True is interpreted as 1 while False as 0 implicitly?

Yes in Python 3, "no" in Python 2, see https://stackoverflow.com/a/2764099/831878 — Ray Toal, Mar 23 '19 at 02:41

False is just a keyword that means int equal to 0. Same for True and 1.
