Question

我有一个类的作业，用于创建一段允许用户输入单词的代码，它将返回包含＆＃39; i＆＃39;或者是＆＃39; a。但是，如果用户输入＆＃34;退出＆＃34;，程序将停止。我只是不断要求输入，即使休息应该已经停止了。

wordprintA = [0]
wordprintI = [0]
dontprint = [0]
while True:
wordlist = [input("Enter a word:").upper()]

for char in wordlist:
    if char == 'A':
       wordprintA.append(wordlist)

for char in wordlist:
    if char == 'I':
       wordprintI.append(wordlist)

else:
      dontprint.append(wordlist)

for char in wordlist:
    if char == 'EXIT':
       break
print(wordprintA, wordprintI)

任何见解都会有所帮助。

中断让你退出for循环而不是while循环。您需要更改while循环以检查绑定到char出口的变量或者第二次检出for循环。见下面的例子

check=true
while check==true:
   wordlist = [input("Enter a word:").upper()]

   for char in wordlist:
      if char == 'A':
         wordprintA.append(wordlist)

   for char in wordlist:
      if char == 'I':
         wordprintI.append(wordlist)

      else:
         dontprint.append(wordlist)

   for char in wordlist:
      if char == 'EXIT':
         check=false
         break
   print(wordprintA, wordprintI)

为什么我的while循环在我添加休息后继续要求输入？
