Python for loop vs while loop Thefor loopis usually used in the sequence when the number of iterations is known. For example, # loop is iterated 4 timesforiinrange(4):print(i) Run Code Output 0 1 2 3 Thewhileloo
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 just put an X on the grid so the user knows he already tried that place. Line 40 takes away one torpedo. Lines 42 ...
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...
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...
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...
Example: while loop with if-else and break statement x = 1; s = 0 while (x < 10): s = s + x x = x + 1 if (x == 5): break else : print('The sum of first 9 integers : ',s) print('The sum of ',x,' numbers is :',s) ...
If the passwordiscorrect, thewhileloop will exit. If the password isnotcorrect, thewhileloop will continue to execute. Info:To follow along with the example code in this tutorial, open a Python interactive shell on your local system by running thepython3command. Then you can copy, paste, ...
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") ...
Python 使用 while 循环打印 1 到 10 Python3 实例 我们将使用 Python 的 while 循环来打印从 1 到 10 的数字。while 循环会一直执行,直到给定的条件不再满足为止。 实例 [mycode4 type='python'] i = 1 while i..
A block of code that you want to execute repeatedly That's all it takes! 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 ...
