getting words from readline

[Adam]

How is best to extract word strings from a
line = infile.readline()

I wish to quickly check the first word of
each line of a text file.

Indeed, How do I break a lineinput() line
into component words (separate by spaces etc) ?

Should I be looking at;
Re Parser Slice StringIO ?


Any help appreciated.

Python 2.4.1 (#1, May 27 2005, 18:02:40)
[GCC 3.3.3 (cygwin special)] on cygwin
Type "help", "copyright", "credits" or "license" for more information.

>>> s = "This is a line of text"
>>> s.split() ['This', 'is', 'a', 'line', 'of', 'text']
>>> l = s.split()
>>> l[0] 'This'
>>>

As you can see above, you probably don't need any complicated modules
for this fairly simple requirement. If you are wanting to match the
words against each other, or against some pre-exisitng list, you might
want to reduce the input to lower-case first.

Ouch. That is simple with .split

I must have got confused amongst
slice re etc. searching searching.

Thanks folks. Painless.
