[Tutor] script error question [checking for substrings]

I meant to add to my last message that the find() solution is 
not without problems too. If you want to find a "word" rather 
than a partial word the splity() method works better:

>>> "Hell" in "Hello from Hell".split()
1
>>> "Hello from Hell".find("Hell") != -1
1
>>> "Hell" in "Hello from Heaven".split()
0
>>> "Hello from Heaven".find("Hell") != -1
1

Of course for this type of search a regular expression is 
probably better still!
