While Loops

Use `while` when you don't know the number of iterations in advance.

Patterns

while queue:
    job = queue.pop(0)
    handle(job)

while True:
    data = stream.read()
    if not data:
        break

Tips

• Always ensure the loop condition eventually becomes False.
• Use break to exit sentinel loops.
• Combine with sleep() or asyncio for polling.
