Re: [Python-ideas] Positional only arguments

Question on it, the example. Is this not a feature of all UserDict subclasses? Yet we have that anyway.
from UserDict import * class C(UserDict): ... pass ... c= C( a=1, b=2 ) print c {'a': 1, 'b': 2} c.update( self=3 ) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: update() got multiple values for keyword argument 'self'
Yes, it's a bug still present in UserDict. Using the @positional_only decorator I posted in a separate thread, we can make it work correctly:: >>> class C(object): ... @positional_only ... def __init__(self, container=None, _kwargs=None): ... print container, _kwargs ... >>> C(self=1, container=2) None {'self': 1, 'container': 2} STeVe -- I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a tiny blip on the distant coast of sanity. --- Bucky Katt, Get Fuzzy
