[Python-Dev] partition() (was: Remove str.find in 3.0?)

[Eric Nieuwland]

I have some use cases with:
	cut_at = some_str.find(sep)
	head, tail = some_str[:cut_at], some_str[cut_at:]
and:
	cut_at = some_str.find(sep)
	head, tail = some_str[:cut_at], some_str[cut_at+offset:] # offset != 
len(sep)

So if partition() [or whatever it'll be called] could have an optional 
second argument that defines the width of the 'cut' made, I would be 
helped enormously. The default for this second argument would be 
len(sep), to preserve the current proposal.
