Introduction to Functions in Python
Functions are the fundamental building blocks of programs in Python. They allow you to encapsulate code into reusable blocks, making your programs more organized and efficient. This guide covers the basics of defining functions, using parameters, and understanding return values.
Key Features:
- Named Functions: Create functions that can be called with specific arguments.
- Optional and Default Parameters: Learn how to define parameters that can be omitted or have default values.
- Handler Functions: Understand how to create functions that respond to events or changes in state.
- Lambda Functions: Discover how to use lambda functions for concise function definitions.
Use Cases:
- Mathematical Operations: Create functions for calculations, such as adding numbers.
- Data Processing: Use functions to manipulate and process data efficiently.
- Event Handling: Implement functions that react to user inputs or system events.
