In this lesson, we’ll explore how to control the flow of your Python programs using conditional statements (if, elif, else), loops (for, while), and functions.

In Python, we use if, elif (else if), and else to control conditional flows. They help the program to make decisions based on certain conditions.
age = 20 if age < 13: print("You are a kid.") elif age < 20: print("You are a teenager.") else: print("You are an adult.")
Python has two types of loops - for and while.
for i in range(5): print(i)
counter = 0 while counter < 5: print(counter) counter += 1
Functions are reusable pieces of code. They only run when called and can receive parameters and return data.
# Defining a function def greet(name): return f"Hello, {name}!" # Calling a function message = greet("Alice") print(message) # Prints "Hello, Alice!"
In this lesson, you’ve learned about controlling the flow of your Python programs using conditional statements, loops, and functions. Understanding control flow is crucial in writing dynamic and flexible Python programs.
