In python how can I set multiple values of a list to zero simultaneously?

Question

Conceptually, I want to do:

arr[20:] = 0

where arr is a list. How can I do this?

Answer 1

You can make a function that you will pass the array to that will zero out the array. I haven't used Python in a while, so I won't attempt to show you the Python code. In that function you could use a for or while loop to iterate through each value and setting each one equal to zero.
