Hello!
A variation of Kent's approach might be to use the 'tokenize' module:
http://www.python.org/doc/lib/module-tokenize.html
which takes advantage of Python's tokenizer itself to break lines into
chunks of tokens. If you intend your input to be broken up just like
Python tokens, the 'tokenize' module might be ok:
######
>>> import tokenize
>>> from StringIO import StringIO
>>> def getListOfTokens(s):
... results = []
... for tokenTuple in tokenize.generate_tokens(StringIO(s).readline):
... results.append(tokenTuple[1])
... return results
...
>>> getListOfTokens('Hi "Python Tutors" please help')
['Hi', '"Python Tutors"', 'please', 'help', '']
######
(The last token, the empty string, is EOF, which can be filtered out if we
use the token.ISEOF() function.)
I'm not sure if this is appropriate for Marilyn's purposes though, but I
thought I might just toss it out. *grin*
