I've stated it returns old value that I've input first time, anyway
output is also inluded in a paste but since you've asked:
def question():
ask = input("Are you OK?:").lower()
if ask != 'yes':
question()
return ask
print (question())
#output:
Are you OK?:no
Are you OK?:no
Are you OK?:yes
no
---------------------------------------
#Another way with 'elif' statment returns none
def question():
ask = input("Are you OK?:").lower()
if ask != 'yes':
question()
elif ask == 'yes':
return ask
print (question())
#output:
Are you OK?:no
Are you OK?:yes
None
#Tried also nested
functions, same results:
def question():
ask = input("Are you
OK?:").lower()
def
check_question(n):
if ask
!=
'yes':
question()
else:
return
ask
m
=
check_question(ask)
print
(m)
question()
#output:
Are
you
OK?:no
Are
you
OK?:yes
None
