The Python standard library contains well over 200 modules. We can import a module according to our needs. Suppose we want to get the value of pi, first we import the math module and use math.pi. For example, # import standard math module import math # use math.pi to get value of ...
Passing two-Oflags to the Python interpreter (-OO) will cause the bytecode compiler to perform optimizations that could in some rare cases result in malfunctioning programs. Currently only__doc__strings are removed from the bytecode, resulting in more compact.pyofiles. Since some programs may r...

1.首先是 python.c,这个文件很短,只是提供了一个 main() 函数。你运行 python 命令的时候,就会先进入这里。 2.接着进入 Modules/main.c 文件,这个文件里提供了运行环境的初始化等功能,它能执行一个 python 文件,也能启动 REPL 提供一个交互式界面。
:param optimize: The optimization level for the compiler. Valid values are -1, 0, 1 and 2. A value of -1 means to use the optimization level of the current interpreter, as given by -O command line options. :return: Path to the resulting byte compiled file. ...
