>>> while True: print(0) 0 0 0 0 0 0 0 0 0 0 0 0 0 Traceback (most recent call last): File "", line 2, in print(0) KeyboardInterrupt The loop runs until CTRL + C is pressed, but Python also has a break statement that we can use directly in our code to stop this type of loop. A while loop statement in Python programming language repeatedly executes a target statement as long as a given condition is true.. Syntax. And so long as this condition is true, the countdown will decrease by intervals of 1. How to use "For Loop" In Python, "for loops" are called iterators. To make the condition True forever, there are many ways. But unlike while loop which depends on condition true or false. Python Infinite While Loop. while expression: statement(s) Here, statement(s) may be a single statement or a block of statements. Python allows an optional else clause at the end of a while loop. Syntax while if. Just like while loop, "For Loop" is also used to repeat the program. This continues till x becomes 4, and the while condition becomes false. Python only provides while loops. x = 6 while x: print (x) x … I won’t consider “[code ]while True:[/code]” always as a bad coding style with Python. To make a Python While Loop run indefinitely, the while condition has to be True forever. Here is the full Python code to perform the while loop for our example: countdown = 10 while countdown > 3: print ('CountDown = ', countdown) countdown = countdown - 1 Once you run the code, you’ll get the following countdown: The condition is true, and again the while loop is executed. C provides while loops and do while loops. In this tutorial, we will learn some of the ways to create an infinite while loop, with the help of example Python programs. while True: n = raw_input("Please enter 'hello':") if n.strip() == 'hello': break Python docs about while loop How to Exit a While Loop with a Break Statement in Python. We generally use this loop when we don't know the number of times to iterate beforehand. Here is a quick guide on how to create an infinite loop in python using a ‘while true’ statement. In the while … So a while loop should be created so that a condition is reached that allows the while loop to terminate. This may be when the loop reaches a certain number, etc. The syntax of a while loop in Python programming language is −. The while loop in Python is used to iterate over a block of code as long as the test expression (condition) is true. While True → Loop will run forever unless we stop it because the condition of while is always True.. We can stop it using break statement. Question or problem about Python programming: def play_game(word_list): hand = deal_hand(HAND_SIZE) # random init while True: cmd = raw_input('Enter n to deal a new hand, r to replay the last hand, or e to end game: ') if cmd == 'n': hand = deal_hand(HAND_SIZE) play_hand(hand.copy(), word_list) print elif cmd == 'r': play_hand(hand.copy(), word_list) print elif […] The condition may be any expression, and true is any non-zero value. Syntax of while Loop in Python while test_expression: Body of while. The else clause will be executed when the loop terminates normally (the condition becomes false). In this article, we show how to exit a while loop with a break statement in Python. In a while loop, the test condition is checked first and if it is true then the block of statements inside the loop is executed. while True: # statement (s) If not condition: break; In python, while loop repeatedly executes the statements in the loop if the condition is true. Having True as a condition ensures that the code runs until it's broken by n.strip() equaling 'hello'.
