Indexing strings

[Fred]

Hi everybody

I am searching for a possibility, to find out, what the index for a
certain lettyer in a string is.
My example:

for x in text:
if x == ' ':
list = text[: # There I need the index of the space the
program found during the loop...

Is there and possibility to find the index of the space???
Thanks for any help!

Use the index method, e.g.: text.index(' ').
What exactly do you want to do?

Perhaps you need something at a higher level (though you could use
text.find(" ") for the first occurrence). I suspect you might want
split(). Fred, meet split(). split(), meet Fred.

>>> s = "The quick brown python swallows the lazy mongoose"
>>> s.split() ['The', 'quick', 'brown', 'python', 'swallows', 'the', 'lazy', 'mongoose']
>>> s.split(None) ['The', 'quick', 'brown', 'python', 'swallows', 'the', 'lazy', 'mongoose']
>>> s.split(None, 3) ['The', 'quick', 'brown', 'python swallows the lazy mongoose']
>>> s.split(None, 1) ['The', 'quick brown python swallows the lazy mongoose']
>>>

That was exactely what I was searching for. I needed a program, that
chopped up a string into its words and then saves them into a list. I
think I got this done...

There's a function for that: text.split().
You should really have a look at the Python docs. Also,
http://diveintopython.org/ and http://www.gnosis.cx/TPiP/ are great
tutorials.
