This field is inherited by static subtypes, but not by dynamic subtypes (subtypes created by a class statement). Default: For dynamic subtypes, this field is always set to PyType_GenericAlloc(), to force a standard heap allocation strategy. For static subtypes, PyBaseObject_Type uses PyType...
adding various small but useful enhancements to the core language, and expanding the standard library. The new object model introduced in the previous version has benefited from 18 months of bugfixes and from optimization efforts that have improved the performance of new-style classes. A few new ...

contextlib模块的文档。 PEP 366: 从主模块显式相对导入¶ Python's-mswitch allows running a module as a script. When you ran a module that was located inside a package, relative imports didn't work correctly. The fix for Python 2.6 adds a__package__attribute to modules. When this attribu...
Python is a general-purpose, interpreted, object-oriented, high-level programming language with dynamic semantics. But what do these terms mean? Let’s break them down individually. General-purpose.Python is not associated with a particular industry or domain. It covers a wide range of tasks and...
