Here, the condition of the while loop is alwaysTrue. However, if the user entersend, the loop termiantes because of thebreakstatement. Pythonwhileloop with anelseclause In Python, awhileloop can have an optionalelseclause - that is executed once the loop condition isFalse. For example, coun...
For example the following code never prints out anything since before executing the condition evaluates to false. x = 10; while (x < 5): print(x) x += 1 CopyFlowchart: The following while loop is an infinite loop, using True as the condition:x = 10; while (True): print(x) x +...
Sometimes we want a part of the code to keep running, again and again, until we are ready for it to stop. Let’s see how while loops can help us do this! Python While 1 Run the example: In this code, we import time so we can use a “wait” function called sleep() . Then, ...
ExampleGet your own Python Server Print i as long as i is less than 6: i =1 whilei <6: print(i) i +=1 Try it Yourself » Note:remember to increment i, or else the loop will continue forever. Thewhileloop requires relevant variables to be ready, in this example we need to def...
An example of an infinite loop: while 1==1: print("In the loop") This program would indefinitely print "In the loop". You can stop the program's execution by using the Ctrl-C shortcut or by closing the program. 无限循环是一种特殊的while循环;它从不停止运行。它的条件总是正确的。
For example, say that you want to implement a number-guessing game. You can do this with a while loop: Python guess.py from random import randint LOW, HIGH = 1, 10 secret_number = randint(LOW, HIGH) clue = "" # Game loop while True: guess = input(f"Guess a number between {LO...
We can create an infinite loop using while statement. If the condition of while loop is alwaysTrue, we get an infinite loop. Example #1: Infinite loop using while # An example of infinite loop# press Ctrl + c to exit from the loopwhileTrue: ...

How To Make A While Loop in Python Now that you know what you need to construct a while loop, all that is left to do now is to look at a real-life example where the while loop is used before you start making exercises on your own! Consider the following example: # Take user input...
print(f"This is loop number {count + 1}") 在上述代码中,使用了for循环,遍历范围为range(max_count),即从0到max_count-1。在每次循环中,打印当前循环次数。这样可以实现与计数器变量相同的效果。 三、使用break语句 还有一种方法是使用break语句,在while循环中手动控制循环次数。通过在循环体中判断计数器是否...
