Break and Continue

Break and Continue

Welcome back to the Control Flow lesson! Today, we'll learn how to control your loops more effectively using the break and continue statements.

Break and Continue are statements that help you control the flow of loops in your programs.

• Break: Exits the loop immediately.
• Continue: Skips the current iteration and moves to the next one.

These statements make your loops more flexible and powerful.

The break statement stops the loop entirely, even if the loop's condition is still true. It's useful when you want to exit the loop based on a specific condition.

Syntax:

if condition:
    break  # Exits the loop

Let's see how the break statement works with a simple example.

Example:

# Iterates through numbers 1 to 5
for num in range(1, 6):
    if num == 3:
        break  # Exits the loop when num is 3
    print(num)  # Prints the current number

When you run the above code, Python will print the numbers until it reaches 3, then it will exit the loop:

1
2

The continue statement skips the current iteration of the loop and moves to the next one. It's useful when you want to skip certain conditions without stopping the entire loop.

Syntax:

if condition:
    continue  # Skips to the next iteration

Here's how the continue statement works with a simple example.

Example:

# Iterates through numbers 1 to 5
for num in range(1, 6):
    if num == 3:
        continue  # Skips the number 3
    print(num)  # Prints the current number

You've learned how to use break and continue statements to control your loops in Python. These tools help you manage how your loops execute, making your programs more efficient and effective.

Keep practicing by incorporating these statements into your own loops to see how they can enhance your programs!
