返回代碼while循環

Question

我在while循環的簡單代碼中遇到問題。我的問題在代碼註釋中解釋。

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 

非常感謝。

Answer 1

我想你在找什麼是continue和break聲明。

continue將中斷當前的迭代（當然，新的迭代開始）。

break會中斷最小的封閉循環。

這兩個聲明也適用於for。

看一看here作爲參考。

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 

如果設置outer到False的地方，它將結束在下次迭代while循環。
