Day 5: Functions and Modular Programming

Task

Create and use functions in Python.

Learning Resources

I don’t know how functions work in Python, so let’s learn together!

Description

Functions are an essential part of Python, allowing you to break down your code into reusable blocks. Using functions helps to keep your code clean, organized, and easier to manage. Functions can take inputs, process them, and return outputs. By modularizing your code, you can avoid repetition and improve maintainability.

Key Concepts

  • Defining Functions: Use the def keyword to define a function
  • Calling Functions: Execute a function by calling its name

Example

# Define a function to greet a user
def greet(name):
    return f"Hello, {name}!"

# Calling the function
print(greet("Alice"))

Output:

1

Hello, Alice!
