Built-in modules (1.8)

Explore the powerful world of Python's built-in modules and functions in Chapter 1.8 of our Python Essentials series! This video guides you through essential tools that come standard with Python, allowing you to write more efficient and versatile code. You'll learn about:

Core Built-in Functions: Discover fundamental functions like print() for output, len() for size, type() for inspection, and int(), float(), str(), bool() for type conversion. We'll also cover sum(), max(), min() for aggregations, abs() for absolute values, round() for numerical precision, and dir() and help() for exploring Python's capabilities.
Essential Built-in Modules: Understand how to import and utilize key modules such as:
math: For mathematical operations like sqrt(), ceil(), and floor().

random: For generating random numbers and making random choices.
datetime: For working with dates and times.
os: For interacting with the operating system and file paths.
sys: For system-specific parameters and functions.
json: For handling JSON data.
collections: For specialized container datatypes like Counter.
re: For powerful regular expression operations.

Import Techniques: Learn different ways to import modules and their components, including from ... import ... and using aliases with as.

Designed to be over 3 minutes long, this video provides practical examples and clear explanations to help you leverage Python's rich standard library effectively.
