30 sty 2013 · The condition that causes a while loop to stop iterating should always be clear from the while loop line of code itself without having to look elsewhere. Phil has the "correct" solution, as it has a clear end condition right there in the while loop statement itself.
There is a much simpler way to use the time condition directly: import time # timeout variable can be omitted, if you use specific value in the while condition timeout = 300 # [seconds] timeout_start = time.time () while time.time () < timeout_start + timeout: test = 0 if test == 5: break test -= 1.
In this Python tutorial, we will learn how to break a While loop using break statement, with the help of example programs. Python – While Loop with Break Statement. Python While Loop executes a set of statements in a loop based on a condition.
break Statement with while Loop. We can also terminate the while loop using the break statement. For example, i = 0 while i < 5: if i == 3: break print(i) i += 1. Run Code. Output. 0. 1.
In this tutorial, you'll learn about indefinite iteration using the Python while loop. You’ll be able to construct basic and complex while loops, interrupt loop execution with break and continue, use the else clause with a while loop, and deal with infinite loops.
18 sie 2023 · Basic syntax of while loops in Python; Break a while loop: break; Continue to the next iteration: continue; Execute code after normal termination: else; Infinite loop with while statement: while True: Stop the infinite loop using keyboard interrupt (ctrl + c) Forced termination
How it works. The while True creates an indefinite loop. Once you enter quit, the condition color.lower() == 'quit' evaluates True that executes the break statement to terminate the loop. The color.lower() returns the color in lowercase so that you can enter Quit, QUIT or quit to exit the program.
