list of all type names
Hello, Python has one feature that I really hate: There are certain special names like 'file' and 'dict' with a predefined meaning. Yet, it is allowed to redefine these special names as in dict = [1:'bla'] In order to avoid problems in the future, I tried to get the list of all those names, but I could not find it. (The Python Reference Manual only says that there is the type Dictionary in Python, but not that 'dict' is a semi-reserved word.) Can you point me to such a list?

Maybe PyChecker can issue a warning? -- mvh Björn -- http://mail.python.org/mailman/listinfo/python-list

This is not a specific Python feature: If you include a header file
in C that redefines fopen(), wou will probably also run into problems.
dict = [1:'bla']
I would avoid the use of generic names for variables but rather use
dict1 or aDict etc. If you want to avoid a name collision without
the use of naming conventions you could rename __builtins__:
bi = __builtins__
del __builtins__
Then you can define what you like but you will have to reference dict,
list etc. as bi.dict, bi.list, ...
For a fast check simply type e.g.
dict
in the interactive Interpreter. If you get a NameError it is not
built-in. :)

Re: list of all type names
Of course, remember that there are benefits to this, as well. Redefining the built-ins can be useful in some interesting cases.

Except that you should never access __builtins__, and the module is actually called __builtin__.

Typing ``dir(__builtins__)`` in the interpreter was already mentioned. Next advice is: make sure all those names are highlighted in your text editor. If I type ``dict`` it's immediatly colored differently than normal names and I know it's probably not a good idea to rebind this name to something else.
