While Loops in Python

A while loop repeats code as long as its condition remains True. This Block introduces the loop through clear, counter-based examples: counting upward, taking larger numeric steps, and building a countdown. You will see how the starting value, condition, indented body, and counter update work together to control every repetition.

What you will learn:

• Build a while loop with a starting value, condition, colon, and indented body
• Understand that Python checks the condition before every iteration
• Count upward and downward with a changing counter
• Create numeric sequences with different step sizes
• Choose comparisons that include or exclude the final value
• Update the counter so the loop moves toward a False condition

By the end, you will be able to read, trace, and write counter-controlled while loops without losing track of where the numbers are going.
