The only reason to do this would be to work around badly written code, but IMO the cure is worse than the disease at that point. The lookup sequence should probably be something like: 1. type(ob) is cls 2. issubclass(type(ob), cls) 3. ob.__class__ is cls 4. issubclass(ob.__class__, cls) 5. ob.__instancecheck__(cls) Where issubclass() checks __mro__ before calling the subclass check method, and #3 and #4 can be skipped if ob.__class__ is type(ob).

Re: [Python-Dev] r59042 - python/branches/py3k/Modules/xxmodule.c

CC to Python Dev The discussion is about http://svn.python.org/view?rev=59042&view=rev I've carefully studied the docs before I've committed the change. The problem is a well documented compiler issue on Windows. The tp_base slot can't be filled with a type on Windows when the module is compiled with distutils. On Unix the gcc can handle tp_base fine. Since most Python developers are using Linux or Mac OS X and the file isn't covered by a unit test nobody has noticed the problem http://docs.python.org/dev/3.0/extending/newtypes.html#subclassing-other-ty… "When filling out the PyTypeObject() for the Shoddy type, you see a slot for tp_base(). Due to cross platform compiler issues, you can’t fill that field directly with the PyList_Type(); it can be done later in the module’s init() function." I've changed it for two reasons: * The xxmodule.c file is an example and template for developers. It's giving a bad example and it leads to code that doesn't compile on Windows. * I'm working on a very basic unit test to test distutils.core.Extension. I've chosen xxmodule and xxsubtype for the tests. I hope I didn't step over a line with the change. I didn't change the files w/o consulting the documentation first. Christian

Python Library Addition: First-class Procedure Signatures
by Isaac Morland 16 Nov '07

16 Nov '07

For another project (see my previous email on named tuples), I needed to represent procedure signatures, and use them to expand arguments into the dictionary of values that exists when execution of a procedure starts. To my surprise, this capability didn't seem to be provided by the Python library, even though it clearly is present within the Python system somewhere. So I wrote a Signature class. Instances of the class represent all the information present between the parentheses of a procedure definition. Properties are provided to get the information out, and an expand_args method can be called to expand arguments into a dictionary. This expand_args method implements (if I've done it right) the argument conversion part of section 5.3.4 of the Python Reference Manual (http://docs.python.org/ref/calls.html). I've put the code below, but I wonder if the real solution is just to create an interface to already-existing capability? It occurs to me that the implementation is likely to be in the interpreter itself and not written in Python. One possible improvement (and I'm not sure it's better, so I'm just putting it out there): perhaps expand_args should be renamed to __call__. Then essentially a Signature object would be a procedure whose body is just "return locals ()". class Signature (object): def __init__ (self, argnames, excessargs=None, excesskeys=None, defaults=None): self.__argnames = tuple (argnames) self.__excessargs = excessargs self.__excesskeys = excesskeys if defaults is None: defaults = {} self.__defaults = dict (defaults) @property def argnames (self): return self.__argnames @property def excessargs (self): return self.__excessargs @property def excesskeys (self): return self.__excesskeys def defaults (self): return dict (self.__defaults) def expand_args (self, *args, **keys): # Start with defaults result = self.defaults () # Assign positional arguments for i in range (min (len (args), len (self.argnames))): result[self.argnames[i]] = args[i] # Assign keyword arguments for arg in self.argnames: if arg in keys: if arg in result: raise TypeError result[arg] = keys[arg] del keys[arg] # Check for missing arguments for i in range (len (args), len (self.argnames)): if not self.argnames[i] in result: raise TypeError # Excess positional arguments (*args parameter) if self.excessargs is None: if len (args) > len (self.argnames): raise TypeError else: result[self.excessargs] = args[len (self.argnames):] # Excess keyword arguments (**keys parameter) if self.excesskeys is None: if keys: raise TypeError else: result[self.excesskeys] = keys return result Isaac Morland CSCF Web Guru DC 2554C, x36650 WWW Software Specialist

for loop with if filter
by Gustavo Carneiro 16 Nov '07

16 Nov '07

I am finding myself often doing for loops over a subset of a list, like: for r in results: if r.numNodes != numNodes: continue # do something with r It would be nice if the plain for loop was as flexible as list comprehensions and allowed an optional if clause, like this: for r in results if r.numNodes == numNodes: # do something with r Has this idea come up before? Does anyone else like this idea? -- Gustavo J. A. M. Carneiro INESC Porto, Telecommunications and Multimedia Unit "The universe is always one step beyond logic." -- Frank Herbert
