Introduction to Python #12 - Modules

In Lecture 12, the last of our Introduction to Python Programming course, we will dive into the concept of modules. A module is a file that contains Python variables, functions, and classes, which can be imported and used in other scripts. Understanding how to create, import, and utilize modules is crucial for building modular and reusable code.

Prerequisites:
Make sure to have a computer with a DRAM capacity of 2GB or higher and a CPU featuring 2 or more physical cores. You'll need an internet connection with a speed of at least 100 Mbps to support video lectures (minimum requirement: 10 Mbps). Ensure you have Python version 3.6 or above installed. Additionally, have a keyboard, mouse, and monitor available to watch the video lectures. It is recommended to use Ubuntu 20.04.2 LTS as your operating system.

Lecture 12: Modules:

• Introduction to modules and their role in Python programming.
• Importing modules and accessing their variables, functions, and classes.
• Exploring different ways of importing specific classes or functions from a module.
• Using imported functions or classes with different names through aliases.
• Importing modules from folders and subdirectories.
• Working with standard modules provided by Python, such as the "os" module.
• Exploring useful functions in the "os" module, including getcwd(), chdir(), rename(), mkdir(), listdir(), remove(), and rmdir().
• Understanding common types of errors: syntax errors, runtime errors, semantic errors, and exceptions.
• Handling exceptions using the "try ~ except" statement.
• Utilizing the "pickle" module to store and read data structures.
• Copying mutable data types using the "copy" module, including lists, dictionaries, and classes.
• Exploring mathematical functions available in the "math" module, such as ceil(), floor(), pow(), and sqrt().

By the end of this lecture, you will have a solid understanding of modules in Python. You will know how to create modules, import them into other scripts, utilize their variables and functions, handle errors using exception handling, work with the "os" module for file system operations, use the "pickle" module for data storage, copy mutable data types, and utilize mathematical functions from the "math" module.
