I would like to see how to view the code behind these modules, such as how randint from random works, etc.

import pandas
import random

For example:

print(pandas.file)
print(random.file)

CodePudding user response：

The source code for most built-in Python modules is located on GitHub, in the python/cpython repository.

The source code for third-party modules (which is what pandas is) can typically be found on a link on their PyPI page (https://pypi.org/project/<module name>).

For example:

• pandas module source code (from here)
• random module source code (from here)

Many modules, such as pandas, are actually a large collection of files, so there is not one file containing every function.

In some cases, however, you can use inspect.getsource (a Python built-in function) to return a string containing the source code for the object:

>>> import inspect
>>> import random
>>> print(inspect.getsource(random))
"""Random variable generators.

    bytes
    -----
           uniform bytes (values between 0 and 255)

    integers
    --------
           uniform within range

    sequences
    ---------
           pick random element
           pick random sample
           pick weighted random sample
           generate random permutation

This will print the file path on your machine where Python is importing those modules from.

import pandas
import random
print(pandas.__file__)
print(random.__file__)

Output:

C:\Users\xxxx\Anaconda3\lib\site-packages\pandas\__init__.py
C:\Users\xxxx\Anaconda3\lib\random.py

You can go to those files and view the source code.
