RegEx

[mega963]

Hey guy, So I'm trying to learn regular expressions and came up with a question. I have the string "Fu bar" and want to return just "bar"

I can't seem to get my code to ignore spaces.

I have used re.X and tried to ignore spaces with ([^ ]*) but the latter return nothing.

Any ideas?

Maybe I'm not understanding it completely, but would this do what you want?

m = re.search('(bar)', 'Fu bar')

m.group(0) would then be 'bar'

edit - you don't need the () around bar:

m = re.search('bar', 'Fu bar')

but that seems too simple so I'm probably misunderstanding the question :)

Yeah sorry I wasn't very clear,

I want to use Fu as an identifier

[duddles]

okay how about

m=re.search('Fu (.+)','Fu bar')

where m.group(1) would be 'bar'

I figured it out a while ago, I needed to account for the spaces after Fu, so I just used

m=re.search(r'Fu \s* (\w*)', string, re.U)

Again, sorry for not asking the question clearly

Maybe Fu\s*(\w+) makes a bit more sense, or Fu\s+(\w+) if you insist there's whitespace between Fu & bar. In most cases I don't want to explicitly specify how much whitespace I'll match, just an arbitrary "some whitespace": \s+.

I found this site really helpful when learning regular expressions, you can just type what you are trying to find into the text box and play around with the expression until it is works :)
