Hi all, I'm new to programming (thus Python), so after reading the basics, I wanted to practise what I've learnt . I've come across a beginners exercise which is to write the code for rot13. I've written some code but it doesn't seem to work.... When I run it I get this error:
NameError: global name 'rot13_char' is not defined Here it is: def rot13(s): char_low = () result = "" if not s.isalpha(): return char char_low = char_low.lower() if char_low <= 'm': dist = 13 else: dist = -13 char = chr(ord(char) + dist) def rot13(string): return ''.join( rot13_char(char)for char in string ) Any ideas where i'm wrong?
