How can i remove (none ) in myresult:

Question

How do I remove that NONE at the end

import textwrap

def wrap(string, max_width):
    l = len(string)
    sp = 0
    diff = 4
    case = True
    while case:
    print(string[sp:diff],end="\n")
    sp = sp + 4
    diff = diff + 4
    if diff>l:
        print(string[sp:])
        case = False


if __name__ == '__main__':
    string, max_width = input(), int(input())
    result = wrap(string, max_width)
    print(result)
    # cannot modify this part of code

Expected:

ABCD
EFGH
IJKL
MNOP
QRST
UVWX
YZ

MY RESULT:
ABCD
EFGH
IJKL
MNOP
QRST
UVWX
YZ
NONE

Answer 1

your wrap function is printing your results

since there is no return from the function you are getting None

instead of this:

if __name__ == '__main__':
string, max_width = input(), int(input())
result = wrap(string, max_width)
print(result)

do this:

if __name__ == '__main__':
string, max_width = input(), int(input())
wrap(string, max_width)
# result = wrap(string, max_width)
# print(result)

your wrap function is not returning anything so no need to store it's output
