Learn to create reusable and modular Python functions with flexible parameters and variable scope
Action Steps
- Define a Python function with default and keyword-only parameters using the syntax `def function_name(param1, param2='default_value')`
- Use the `*args` and `**kwargs` syntax to handle variable numbers of arguments
- Understand the rules of variable scope in Python to avoid common pitfalls
- Create a higher-order function that takes another function as an argument to demonstrate first-class citizen functionality
- Apply functional programming principles to create dynamic utilities

Welcome to Day 3! Today, we transition from writing basic scripts to building reusable, modular, and highly flexible building blocks . We will look at how Python handles arguments, the strict rules of variable scope, and how functions can be treated as first-class citizens to create highly dynamic utilities. ๐ 1. Parameters & Arguments (Default & Keyword-Only) โ๏ธ In Python, you can define parameters that make your functions incredibly flexible. <
