Loop Control Patterns

1Understanding Loop Control✨

Loop control patterns allow you to manage how loops behave, making them more powerful and flexible. In Python, you can use the `break`, `continue`, and `else` statements to control your loops effectively.

2Using Break🎯

The `break` statement stops a loop immediately when a certain condition is met. This is useful when you want to exit a loop early.

3Example:💡

for number in range(10):
    if number == 5:
        break
    print(number)

This code will print numbers from 0 to 4, then stop when it reaches 5.

4Using Continue🚀

The `continue` statement skips the current iteration and moves on to the next one. This is helpful when you want to ignore specific values.

5Example:🔍

for number in range(10):
    if number % 2 == 0:
        continue
    print(number)

This code will print only odd numbers from 0 to 9.

6Using Else with Loops⭐

You can also use the `else` statement with loops. The code inside the `else` block runs only if the loop completes without hitting a `break`.

7Example:🧩

for number in range(5):
    print(number)
else:
    print("Loop finished without interruption")

This will print numbers from 0 to 4, followed by "Loop finished without interruption".

8Combining Patterns🎈

You can combine these control patterns to create more complex logic. For example, you could skip certain numbers and stop the loop based on a condition.

9Example:✨

for number in range(10):
    if number == 7:
        break
    if number % 2 == 0:
        continue
    print(number)

This will print 1, 3, 5, and 9, stopping at 7.

10Challenge Yourself🎯

Try creating a program that asks for user input to find prime numbers within a given range. Use `break` to exit the loop if the user enters a negative number and use `continue` to skip even numbers for efficiency!

Happy coding!
