Python’s interactive shell comes with a lot of built-in functions, so we already know that. Because they’re part of the shell, functions like these are always ready to use: print () and input () for I/O (input/output), functions for converting numbers like int (), float (), complex (), functions for converting data types such as list (), tuple (), set (), etc.
In addition to these many built-in functions, there are also a lot of pre-made functions that come with Python distributions. These modules are called built-in modules because they have these functions already built into them.
They are written in C language and are part of the Python shell.
If you want to see a list of all of the available modules in Python Programming Language, you can ask Python to tell you. Type in the following code in the Visual studio code:
help('modules')The output to the above code is shown below:
Please wait a moment while I gather a list of all available modules...

We cannot simply use all of these many modules! In fact, I don’t know most of them myself. However, there are some useful and frequently used built-in modules of Python.
- Math Module
- Statistics Module
