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...
The else Clause In While Loop Python provides unique else clause to while loop to add statements after the loop termination. This can be better understood by the following example, x =1while(x<=3):print(x) x = x +1else:print("x is now greater than 3") ...
Example Program with While Loop Now that we understand the general premise of awhileloop, let’s create a command-line guessing game that uses awhileloop effectively. To best understand how this program works, you should also read aboutusing conditional statementsandconverting data types. First, ...
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...
Then, it lets the player pick a place to shoot the torpedo. We validate this input so it doesn’t break our program. After that, we test what the user entered to see if it matches the ship’s location. If it does, Python says “It’s a hit!” and ends the loop. Otherwise, we...
解决While loop问题 - Python 当我们在使用while循环时,需要确保循环的终止条件最终会被满足,否则循环将会无限执行下去。通常情况下,我们可以在循环内部修改循环控制变量,使得终止条件得以满足。 1、问题背景 一位开发者在使用 Python 开发一个基于文本的游戏时,遇到了 while 循环的问题。他将游戏代码和音频处理代码...
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。
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...
The basic loop structure in Python is while loop. Here is the syntax.Syntax:while (expression) : statement_1 statement_2 ...The while loop runs as long as the expression (condition) evaluates to True and execute the program block. The condition is checked every time at the beginning of...
Python does not have a built-in "do-while" loop, but you can emulate its behavior. Emulating Do-While Behavior To emulate a "do-while" loop in Python, you can use a while loop with a True condition and strategically place a break statement. Here's an example: while True: # Execute...
