Question

我有一本像这样的字典，

replies = {'0':'Leave it out to dry for 24 hours, if it does not work see customer service',
           '1':'Go to a repair store to get it fixed',
           '2':'Charge the phone battery',
           '3':'Try resetting the phone',
           '4':'Check to see if something blocking the audio jack or the speakers',
           }

我有int(input(,我希望用户输入一个数字来打印字典中的值，我试过print(replies[number the user input])

但它不起作用，感谢任何帮助，也不是我不是很有经验，所以简单有帮助，谢谢

Answer 1

如果您想使用数字（整数）作为密钥，您需要获得如下数据：

replies = {0: 'Leave it out to dry for 24 hours, if it does not work see customer service',
           1: 'Go to a repair store to get it fixed',
           2: 'Charge the phone battery',
           3: 'Try resetting the phone',
           4: 'Check to see if something blocking the audio jack or the speakers',
           }

在这种情况下，它可能更好地使用列表并通过索引访问您的数据。

Answer 2

replies = {'0':'Leave it out to dry for 24 hours, if it does not work see customer service',  
               '1':'Go to a repair store to get it fixed',  
               '2':'Charge the phone battery',  
               '3':'Try resetting the phone',  
               '4':'Check to see if something blocking the audio jack or the speakers',
               }

你的索引不是整数，这就是为什么你可以说打印回复[1]

只需将字典更改为

replies = {0:'Leave it out to dry for 24 hours, if it does not work see customer service',
           1:'Go to a repair store to get it fixed',
           2:'Charge the phone battery',
           3:'Try resetting the phone',
           4:'Check to see if something blocking the audio jack or the speakers',
           }

Answer 3

这个正在运作....试试这个......

 input1=raw_input("Enter number ")
 print replies[input1]

您正在尝试将输入键转换为整数....但是回复字典键是在字符串....

从用户输入打印值
