Core Python Crash Course (Modules)

As I mentioned before those crash courses are not for ultimate beginners. If it is your first time to code I don't support reading this Topic. If you are a programming Fan, you would Like it.

It is a crash course of a course on Udemy. In this topic, we will discuss:

1. Modules:

Modular Programming means breaking a large programming task into separate, smaller modules.
Advantages of Modules: 1) simple: It doesn't focus on the whole problem but a specific part of it. This makes development easier and less error-prone.
2) Maintainability: It focuses on a specific domain and minimizes the interdependency of those modules.
3) Reusability 4) Scoping: For each its namespace.

Functions, modules, and packages are all constructs in Python that promote code modularization.
There are 3 types of Python modules ( Written in Python itself, Written in C and loaded at runtime, built-in modules)

We focus now on The built-in modules:
This is how to call a module.

1. import (module name).
2. s and foo are in the module (private symbols) They are like functions.


The built-in function dir() returns a list of defined names in a namespace. Without arguments, it produces an alphabetically sorted list of names in the current local symbol table

import mod
>>> dir(mod)

Different ways to call a module: 

import (module name)  as (abbreviation)
(abbreviation).(Private symbol) OR  from (module name) import*
