The while Loop
Explore how to use the while loop in Python to perform repetitive operations while conditions remain true. This lesson teaches you to structure while loops safely, handle dynamic data, apply break and continue statements, and avoid infinite loops. You will gain practical skills to write efficient and controlled looping code for various programming scenarios.
The while loop keeps iterating over a certain set of operations as long as a certain condition holds True. It operates using the following logic:
While this condition is true, keep the loop running.
Structure
In a for loop, the number of iterations is fixed since we know the size of the sequence. On the other hand, a while loop is not always restricted to a fixed range. Its execution is based solely on the condition associated with it.
The while loop in action
Here's a simple example of a while loop in Python that prints the numbers from 1 to 5. Note that the while statement also ends in a colon, similar to the ...
