Is there a way to list out in-built variables and functions of Python

Question

Hi. I recently found out about the dir() method that lists out the names that a module provides. To use this, you need to import a module and then use the dir() method. 

import datetime
dir(datetime)

I was just wondering if there is a way to list out the in-built functions. Because, we don't import any module to use the in-built functions or names, so how can we list the in-built names?

Answer 1

The in-built variables and functions are defined in the builtins modules. So you can use the dir() method on this module to list the names. For example:

>>> import builtins
>>> dir(builtins)
