Study Notes

Module Overview

A module in Python is a file that contains definitions and statements, allowing for organized code management.

Importing Modules

The import statement is used to bring modules into a Python script for reuse of code.

Basic Import Syntax

The simplest method to import a module is by using import module_name, for example, import math.

Importing Multiple Modules

Multiple modules can be imported simultaneously using:
- import module_1, module_2
- Or separately defined:
  - import module_1
  - import module_2

Module Functionality

Python checks for the existence and accessibility of the specified module. If found, it imports all defined names, which remain separate from the current namespace.

Using Module Entities

Access an entity from a module by using the syntax: module_name.entity_name, e.g., math.pi.

Name Conflicts

It is possible for imported entities to share names with existing identifiers in the file. Example:
- import math
- def pi(x): return x
- Accessing math.pi resolves to the module's pi.

Importing Specific Entities

Specific functions or variables can be imported using:
- from module import entity_name, e.g., from math import pi.
- Multiple imports can be done as well: from module import pi, sin.

Importing All Entities

To import everything from a module, use:
- from module import *.
- This practice should be temporary due to potential name conflicts.

Aliasing Modules

Modules can be imported under a different name, a process known as aliasing. Example:
- import math as alias
- Access using alias.pi.
- Functions can also be aliased: from module import function_1 as fun.

Best Practices for Imports

The recommended way to import and use functions is:
- from module_1 import function
- Followed by calling the function directly: function().
