同样builtin_methods是一个PyMethodDef数组,以空PyMethodDef结尾。熟悉的print、dir等函数都可在这找到定义。 这类Moudle还有很多,如io模块也是这样实现的。在Modules\_io\_iomodule.c可找到对应的定义。 3.内存中的builtin_function_or_method Python提供了一个叫id的函数,该函数可以查看对应对象在内存中的地址。

This Python dictionary tutorial covers how to define and access values in a dictionary, how to iterate through a dictionary and various dictionary methods.
Return a new array of bytes. The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the str type has, see String Methods. ...
