No idea if anyone will get anything out of this but enjoy.Code:def stringBetween(stringToSearch, startString, endString): #stringBetween by Nat + Monarchy for Python 3.1 initPos = stringToSearch.find(startString) if initPos == '-1': return '' else: initPos = initPos + len(startString) stringLength = stringToSearch.find(endString, initPos) return stringToSearch[initPos:stringLength] #Example usage x = 'this is my [tag]dog[/tag]' y = stringBetween(x, "[tag]", "[/tag]")

[Python 3.1] stringBetween Function

Nice. What happens if you use -1 as the first part of stringToSearch[one:two]?
e.g. stringToSearch[-1:stringLength]
Error? Or does it start at 0 anyway?

What are you even saying? Could be that I'm tired as fuck but that made no sense to me...

x = 'this is my [tag]dog[/tag]'
echo x[-1
en(x)]
I doubt the output function is called echo, but whatever. What is the value of x[-1en(x)]?

An error probably. Why would you even do that that's in no way relevant?

If it defaulted -1 to 0, then the code could be shorted by quite a bit. Just brainstorming.

If a string is not found then the str.find fuction returns -1.

I know. Which is how it could be shortened.
Something along the lines of:
return x[x.find(start):x.find(end)]
And cut out the middle man that checks to see if it found the string, because if -1 defaults to 0 when taking substrings, then it would just return the entire string (or an empty string, like your program is doing now, if `end` isn't found, 'cause it would return x[-1:-1]).

No it wouldn't it would return the last character in the string...

Alright. That's what I was asking.
