Selecting first word of a variable

[Boblert]

How do I select the first word of a variable?[CODE=python]
name = raw_input("What 's your full name? ")
print "Hey, %s, how you doing?" % name[/CODE]

So say I only wanted it to print the first name? How would I do this not knowing the amount of letters in it?

[CODE=python]
>>> name = "Jo Shcmo"
>>> firstandlast = name.split()
>>> firstname = firstandlast[0]
>>> firstname
'Jo'
>>> [/CODE]

Thanks alot,
also how would I create a function to replace but only if its the whole words for example:

Replace:
man : guy

Sentence to be replaced:
That man is good but he ain't no superman.

But I can only get it to replace as:
That guy is good but he ain't no superguy.

But I want it to replace as:
The guy is good but he ain't no superman.


Sorry if that my problem is confusing its hard to explain

Try something like this:
[code=python]
sent = "That man is good but he ain't no superman."
words = sent.split()

for (i, word) in enumerate(words ):
if word == "man":
words[i] = "guy"

newsent = " ".join(word s)
[/code]
You could also use the re module.

Ye, thats what I've been doing. But it is a large word-replace list and large paragraph.
Just thought there might of been a way with less lines used :D
and I don't quite understand the re module

If you have more than one word you can do something like this (don't know if you did it already) ;):
[code=python]
replacedict = {"man": "guy", "woman": "girl", "car": "automobile "} # etc...

for i in range(len(parag raph)):
if paragraph[i] in replacedict.key s():
paragraph[i] = replacedict[paragraph[i]]
[/code]
Technically, that uses the same amount of lines.

and I don't quite understand the re module

A Regular Expression (re), has it's own language. A VERY simple example would be a sub-string followed by any whitespace (pure Python could easily do this to, but "regex"s, as they are called go much further):[CODE=python]>>> import re
>>> s = "That man is good but he ain't no superman"
>>> reObj = re.compile("man \s")
>>> reObj.sub("guy ", s)
"That guy is good but he ain't no superman"
>>> [/CODE]Just thought I'd throw that out there.

read the docs for replace() more carefully. The docs are your good friend.

>>> "This man is a superman".replace("man","guy",1)
'This guy is a superman'
>>> "This man is a superman".replace("man","guy")
'This guy is a superguy'
>>>

"superguy", that's a good one!
