What is the Python standard library What are some of the useful standard library modules?

The Python Standard Library is a collection of script modules accessible to a Python program to simplify the programming process and removing the need to rewrite commonly used commands. They can be used by ‘calling/importing’ them at the beginning of a script.

What is the importance of module library in Python?

A module allows you to logically organize your Python code. Grouping related code into a module makes the code easier to understand and use. A module is a Python object with arbitrarily named attributes that you can bind and reference. Simply, a module is a file consisting of Python code.

To use the functionality present in any module, you have to import it into your current program. You need to use the import keyword along with the desired module name. When interpreter comes across an import statement, it imports the module to your current program.

What are the advantages of using modules in Python?

Advantages of modules –

  • Reusability : Working with modules makes the code reusable.
  • Simplicity: Module focuses on a small proportion of the problem, rather than focusing on the entire problem.
  • Scoping: A separate namespace is defined by a module that helps to avoid collisions between identifiers.

What is the best way to learn Python library?

Over the years I can sum up the way to learn python library into three steps: help(library): The help method is a built-in python help system. It works in interactive mode. So, while developing python programs, fire up a python shell in a terminal and use help() method to get help on modules, functions or any python object.
