The Python Standard Library contains a list of built-in Python modules that are shipped with each Python distribution. Any object on python can be pickled so that it can be saved on disk. You can import only a small part of the module, i.e., only the required functions and variable names from the module instead of importing full code. A file containing Python code, for example: test.py, is called a module, and its name would be test. Here's an . A Python module is a file containing Python definitions and statements. 2.
