在main函数中,通过调用first_loop和second_loop来实现循环的衔接。 二、使用嵌套循环 嵌套循环是一种常见的方法,通过在一个循环内部嵌套另一个循环来实现复杂的循环控制逻辑。以下是一个示例: def main(): while True: print("Inside outer while loop") user_input = input("Enter 'next' to go to the inn...
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). ...
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: Example Continue to the next iteration if i is 3: ...
number =0whilenumber <= 10:ifnumber % 2 ==0:print("The number is even:"+str(number)) number+= 1continueprint("Next...")else: number+= 1else:print("The number is equal or more than 10, stop loop.")'''输出: The number is even: 0 ...
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') ...
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) ...
Python虚拟机首先获得了之前通过SETUP_LOOP指令申请得到的,与当前while循环对应的PyTryBlock结构,然后根据其中存储的运行时栈信息将运行时栈恢复到while循环之后的状态。最后Python虚拟机将why设置为WHY_NOT,表示退出状态没有任何错误,再通过JUMPTO宏,将虚拟机中下一条指令的指示器next_instr设置为距离code开始位置b->b...
把它扔掉。 command = input("You are " + map[curr_loc]["desc"] + ' what next? ')不需要出现在每个子句中,请将它放在if/elif语句链之后。 执行while循环。。现在:无限,目标:不无限(ask until循环) 您没有验证和清除cin流的错误状态。请尝试以下操作: #include <iostream>#include <limits>using ...
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) ...
熟悉Rust和Golang语法的同学肯定对loop用法不陌生,说白了它是While-True的语法糖,即任何写在loop作用域内的代码都会被无限循环执行,直到遇见break。 比如在Golang中可以通过for和大括号的组合实现loop效果—— import"fmt"funcmain(){sum:=0for{sum+=1ifsum==10{break}}fmt.Println(sum)} ...
