The two methods are defined differently, and act as defined, so this is a feature request, not a bug report.
str.split([sep[, maxsplit]])
... If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified, then there is no limit on the number of splits (all possible splits are made).
re.split(pattern, string, maxsplit=0, flags=0)
...If maxsplit is nonzero, at most maxsplit splits occur,
Clearly, if maxsplit for re.split is the default of 0, it must do all splits. There is a difference between being optional with no default (possible with C-coded functions) and with a default.
Logically, both should have a default of None, meaning no limit. But I agree with Ezio and do not see that happening for Python 3.
As for negative values, I would have maxsplit treated as a count and make negative values a ValueError. |
