Exit the loop when i is 3: i =1 whilei <6: print(i) ifi ==3: break i +=1 Try it Yourself » The continue Statement With thecontinuestatement we can stop the current iteration, and continue with the next: Exam
while循环会在满足特定条件时重复执行代码块whilecount = 0 while count < 5: print(count) ...
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 the loop and the first time when the expression evaluates to False, the loop stops without executing any remaining statement(s). ...
while loop < 3: print("Hello world!") # 输出的数据不依赖上一次的数据,因此不是迭代 loop += 1 #迭代: loop = 0 while loop < 3: print(loop)#输出的loop与上一次数据有关 loop += 1 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 2. 可迭代对象(Iterable): (1)可迭代对象并不是指某...
while expression: suite_to_repeat 注解:重复执行suite_to_repeat,直到expression不再为真 2.2.2:计数循环 count=0 while (count < 9): print('the loop is %s' %count) count+=1 2.2.3:无限循环 count=0 while True: print('the loop is %s' %count) ...
while 条件表达式: 执行语句 示例 count = 0 while count < 5: print(count) count += 1 循环控制语句 break 退出循环。 for number in range(10): if number == 5: break print(number) continue 跳过当前循环的剩余语句,继续下一次循环。 for number in range(10): if number % 2 == 0: continue...

If the user enters0, the loop terminates. Infinite while Loop If the condition of awhileloop always evaluates toTrue, the loop runs continuously, forming aninfinite while loop. For example, age =32# The test condition is always Truewhileage >18:print('You can vote') ...

Python while循环是一种用于重复执行特定代码块的循环结构。它会在指定的条件为真时继续执行,并在条件变为假时停止循环。 在执行过程中,可以使用计数器变量来跟踪循环次数,并在达到指定次数后终止...
