How to get the source code of built-in module?

The source code of module or function can be get from inspect .

import inspect
print(inspect.getsource(moduleName.function))

What about if the module is a built_in module?

import sys
print(inspect.getsource(sys))

TypeError: <module 'sys' (built-in)> is a built-in module .

Where can i get it then ?

The sys module is one of the very few ones which are not implemented in Python itself, but in native code instead. The C source is located in /Python/sysmodule.c.

Most of the other modules are directly implemented in Python. You can find the source for those in your lib directory of your Python installation, or also in the source.
