how about
def aaaa():
y = x+1
if y > 1:
return "wrong"
else:
return y
but if you really have to modify x outside of the scope of the function,
well, i guess one possibility is to return a tuple, one element being a
string that may or may not contain the word "wrong" and another being x, and
then whatever's calling aaaa can change x in their own scope based on the
return value. but other than that, the normal way to affect a variable
beyond the scope of your function is to make a class and affect a class
variable. although there is always the 'global' statement also.
