How come my function didn't print a output? [Python]

Question

I created a function to square some numbers. I was wondering why my code didn't print.

def Square(A):
    for i in range(len(A)):
        A[i] = A[i]**2

A = [2,0,-3]

print(Square(A))

The function doesn't return anything, it modifies the list in place. Call the function then do `print(A)` — Barmar, Feb 01 '21 at 22:13
Or add `return A` to the end of the function (outside the loop). — Barmar, Feb 01 '21 at 22:14

Add a return value.

def Square(A):
    for i in range(len(A)):
        A[i] = A[i]**2
    return A

print(Square(A))
