Replace negative values in an numpy array

Question

Is there a simple way of replacing all negative values in an array with 0?

I\'m having a complete block on how to do it using a NumPy array.

E.g.

Answer 1

Another minimalist Python solution without using numpy:

[0 if i < 0 else i for i in a]

No need to define any extra functions.

a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]

yields:

[1, 2, 3, 0, 0, 6]
