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...
An if statement is run once if its condition evaluates to True, and never if it evaluates to False. A while statement is similar, except that it can be run more than once. The statements inside it are repeatedly executed, as long as the condition holds. Once it evaluates to False, the...
The While statement is a type of loop statement. If the condition is met, the internal instruction is executed until the condition is not met. If the condition is not met, the internal instruction is not executed. Here is a piece of code to guess the number. To obtain random numbers, y...

languages = ['Swift', 'Python', 'Go', 'C++'] for lang in languages: if lang == 'Go': break print(lang) Run Code Output Swift Python Here, when lang is equal to 'Go', the break statement inside the if condition executes which terminates the loop immediately. This is why Go and...
whileTrue:ifcondition_1:break...ifcondition_2:break...ifcondition_n:break This syntax works well when you have multiple reasons to end the loop. It’s often cleaner to break out from several different locations rather than try to specify all the termination conditions in the loop header. ...
对于第一个输入示例,如果用户输入ee而不是e,那么它将不会跳出while循环。只有输入e 才会打破while循环。 英文: For the first input example, if the user types ee instead of e, it will NOT break out of the while loop. Only typing e will break the while loop. ...
If the condition is false, the loop is terminated. Similar to if statements, the while loop in Python can also include an else block. The else block is optional and will be executed once if the condition is (or becomes) false. while False: # this code doesn't loop never_runs() else...

如果在块中间不再满足while循环的条件,while循环是否会执行所有代码行? 答案是肯定的。仅在每个循环迭代开始时检查条件。如果要提前结束循环执行,必须执行break语句。 If Else分支不执行-Python3 代码如下&在if语句中使用or和and关键字来确定颜色。 color1 = "red"color2 = "green"def getColor(color1, color2):...
