Python input returns None

Question

When executing this code(simplified) I get None printed in the cmd, while I was expecting it to print out whatever I wrote as an answer to Foo: , and then it prints Bar. Why does this happen?

def contin(message):
    input(message)

answ = contin('Foo: ')
print(answ)
if answ == None:
    print('Bar')

Your function doesn't return anything, so by default it returns None is such cases. You need to return input(message):

def contin(message):
    return input(message)

def contin(message):
    return input(message)

answ = contin('Foo: ')
print(answ)
if answ == None:
    print('Bar')
