Detect and move zero's to end of list

Question

I'm puzzle why the below code does not properly pop and extend the list for each zero it identifies.

def move_zeros(array):
    array.extend([array.pop(i) for i,x in enumerate(array) if x != 0 and x != False])
    return array

Answer 1

The reason you don't get the appropriate result is because you iterate over an array and change his elements simultaneously.

This is bad practice, you should work with another list\variable in order to achieve your goal.
