官网PYthon语言参考手册The Python Language Reference

This reference manual describes the syntax and “core semantics” of the language. It is terse, but attempts to be exact and complete. The semantics of non-essential built-in object types and of the built-in functions and modules are described in The Python Standard Library. For an informal introduction to the language, see The Python Tutorial. For C or C++ programmers, two additional manuals exist:Extending and Embedding the Python Interpreter describes the high-level picture of how to write a Python extension module, and thePython/C API Reference Manual describes the interfaces available to C/C++ programmers in detail.
