Unlocking the Power of While Loops in Python

A while loop is one of Python’s fundamental control structures, allowing you to execute a block of code repeatedly as long as a specified condition remains true. Let’s explore it from the basics to advanced use cases.

1. Basic While Loop Syntax

# Basic while loop example
count = 0
while count < 5:
    print("Count:", count)
    count += 1

Count: 0
Count: 1
Count: 2
Count: 3
Count: 4

Explanation:

The loop runs as long as the condition (count < 5) is True. count is incremented by 1 in each iteration, and the loop exits when count equals 5.

2. Avoiding Infinite Loops

A common mistake is forgetting to update the condition variable, leading to an infinite loop.

count = 0
while count < 5:
    print("This will never end")

To avoid this, ensure that your condition changes in each iteration, allowing the loop to eventually stop.

3. Using break and continue

break stops the loop entirely.

continue skips the current iteration and moves to the next one.

count = 0
while count < 5:
    if count == 3:
        break…
