Python why i got no output here

Question

I recently started learning python and I cannot figure why I got no output from the code below:

def countdown():
    i = 5
    while i > 0:
        return i
        i -= 1
    print (i)

Answer 1

As @alfasin stated in the comments, you bail out of the function by using return before your function does anything.

What you probably intended to do was this:

def countdown():
    i = 5
    while i > 0:
        print(i)
        i -= 1

    return i

Then call the function:

countdown()

Output:

5
4
