Pythonwhileloop withbreakstatement We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, whileTrue: user_input =input('Enter your name:
最后,我们可以通过关系图描述这个过程: EXTERNAL_CONDITIONStringinputBooleanisMetWHILE_LOOPBooleanrunningchecks 结尾 通过以上步骤,我们成功实现了使用 Python 根据外部条件跳出 while 循环的功能。这种设计模式在实际开发中非常有用,能够有效控制程序流。希望这篇文章能够帮助你深入理解这一概念,鼓励你在实际项目中尝试和应...

BOOLEAN { bool value } EXCEPTION { string message } 结论 在Python中,有多种方法可以限制while循环的次数,包括使用计数器、布尔变量和异常处理。选择哪种方法取决于具体的应用场景和个人偏好。通过合理地限制循环次数,我们可以避免无限循环和提高程序的稳定性和效率。
然后结束循环,进入下一个语句。这里我们使用print(Done)来表示已经进入了下一个语句。然后结束程序。这个程序里面,True和False被称作布尔(Boolean)型,我们可以将它们分别等价地视为1与0.多数时候,我们使用while语句去控制程序的时候,我们都没有使用else块。因为当循环结束的时候,我们直接就进入下一个语句了。

Python While 1 Run the example: In this code, we import time so we can use a “wait” function called sleep() . Then, we make a new variable called alive and set it to True. When you make a variable equal to True or False, you are making abooleanvariable. This means it can onl...
The while loop will terminate when the boolean expression returns FALSE. Example 1: R while Loop Let's look at a program to calculate the sum of the first ten natural numbers. # variable to store current number number = 1 # variable to store current sum sum = 0 # while loop to calcul...
