2.3.1 The while Loop

The while loop repeats a block of code as long as a condition remains True.
It is commonly used when the number of iterations is not known in advance.

How the while Loop Works

• The condition is evaluated before each iteration
• If the condition is True, the loop body executes
• If the condition becomes False, the loop stops

---

Common Use Cases

• Repeating actions until a condition is met
• Waiting for a specific state
• Implementing input validation loops

📌 Note:
Always ensure that the loop condition can eventually become False to avoid infinite loops.
