dowhile和while的代码举例 1. do-while 循环 do-while 循环至少会执行一次,即使条件一开始就是 false。以下是一个简单的 Python 示例: python counter = 0 do_while_loop: print(f"Counter: {counter}") counter += 1 if counter > 5: break 在这个例子中,do-while 循环会打印出计数器的值,然后增加...
# python example of to print tables count = 1 num = 0 choice = 0 while True: # input the number num = int(input("Enter a number: ")) # break if num is 0 if num == 0: break # terminates inner loop # print the table count = 1 while count <= 10: print(num * count) ...
Example-2: Emulate the Do-While Loop Using the While Loop Without the ‘If’ Condition Create a Python file with the following script to take a number from the user repeatedly until the user provides a number greater than or equal to 50. Thecheckvariable is set toTrueto start the iteratio...
while(condition){ // statements }Now let us take a simple example and print all the numbers from 0 up to 5. See the example below.// class public class Main { public static void main(String[] args){ // variable defining int num = 0; // while loop java while(num < 5){ // ...
loop --|> execute body loop --|> update variable loop --|> return to check condition 总结 通过本文,你已经学会了如何使用while循环来实现"Python do loop"。首先,你需要初始化一个循环变量,并在每次循环开始之前判断循环条件是否为真。然后,执行循环体内的代码,并在每次循环结束之后更新循环变量。最后,回到...

loops and exit-controlled loops. Thedo-whileloop is an example of the latter. This means that unlike thewhileloop, which is an entry-controlled loop, thedo-whileloop tests the condition at the end of the iteration, and the loop is executed at least one time, regardless of the condition....
Run JavaScript code from Python. PyExecJS is a porting of ExecJS from Ruby. PyExecJS automatically picks the best runtime available to evaluate your JavaScript program. A short example: >>> import execjs >>> execjs.eval("'red yellow blue'.split(' ')") ['red', 'yellow', 'blue']...
