New submission from Alan Grow <[email protected]>:
If you split a string in a maximum of zero places, you should get the original
string back. "".split(s,0) behaves this way. But re.split(r,s,0) performs an
unlimited number of splits in this case.
To get an unlimited number of splits, "".split(s,-1) is a sensible choice. But
in this case re.split(r,s,-1) performs zero splits.
Where's the sense in this?
>>> import string, re
>>> string.split("foo bar baz"," ",0)
['foo bar baz']
>>> re.split("\s+","foo bar baz",0)
['foo', 'bar', 'baz']
>>> string.split("foo bar baz"," ",-1)
['foo', 'bar', 'baz']
>>> re.split("\s+","foo bar baz",-1)
['foo bar baz']
