返回代码while循环

Question

我在while循环的简单代码中遇到问题。我的问题在代码注释中解释。

CODE

exit = False 
    while not exit: 
     choice = input("Test ") 

     if choice== 1: 
      print "hello" 
      exit = False 

     else: 
      print "good morning" 
      #I want to return to the first while with the input Test but I pass to the second while 
      exit = False 


     exit1 = False 
     while not exit1: 
      choice = input("Test 1") 

      if choice== 1: 
       print "bye" 
       exit1 = False 

      else: 
       print "good evening" 
       #I want to return to the first while with the input Test but I return to the second while 
       exit = False 

非常感谢。

Answer 1

我想你在找什么是continue和break声明。

continue将中断当前的迭代（当然，新的迭代开始）。

break会中断最小的封闭循环。

这两个声明也适用于for。

看一看here作为参考。

Answer 2

outer = True 

while outer: 
    do_something 
    if a: 
     continue # will get you back to do_something 
    if b: 
     break # will end the outer loop 

如果设置outer到False的地方，它将结束在下次迭代while循环。
