Abstract
This PEP proposes that symbols matching the type name should be added to the types module for all basic Python types in the types module:
types.IntegerType -> types.int types.FunctionType -> types.function types.TracebackType -> types.traceback ...
The long capitalized names currently in the types module will be deprecated.
Um, can I be a little confused? If you are writing code that you know will be run in 2.2 and later, you write
isinstance(obj, int)
If you want to support 2.1 and so on, you write
isinstance(obj, types.IntType)
What would writing
isinstance(obj, types.int)
ever gain you except restricting execution to 2.3+?
It's like asking what do you gain by using string methods instead of the string module. It's part of a slow, long-term effort to clean up the language while trying to minimize the impact on existing code. Oren
