想最终只打印出红色字部分“a1”，但为啥却是“dict_values(['a1'])”？？
我尝试把字典里的values()放在循环里面，就可以直接得到想要的结果，这

1. import pyperclip
   
2. PASSWORDS = {'sina':{'aa':'a1'},
   
3.            'msn':{'bb':'b2'},
   
4.            'cu':{'cc':'从'}}
   
5. account = input('PLS input WEBSITE:')
   
6. if account in PASSWORDS:
   
7.     # passwd = PASSWORDS[account].values()
   
8.     for i in PASSWORDS['sina'].values():
   
9.         print(i)
   
10.     #pyperclip.copy(passwd)
    
11.     # print("Your " + PASSWORDS[account].keys() + " is copied")
    
12. else:
    
13.     print("account is not valid")
    

复制代码

1. C:\Python\Python35\python.exe D:/PycharmProjects/day1/code.py
   
2. PLS input WEBSITE:cu
   
3. a1
   
4. 
   
5. Process finished with exit code 0

不用循环的话，返回以下这个值，但如果用循环的话，就返回想要的结果。
dict_values(['<font color="#ff0000">a1</font>'])
