從列表中獲取對象的屬性

Question

考慮對象customer和屬性列表attrs。 如何迭代列表以獲取列表中的屬性？

class Human():  
    name = 'Jenny'   
    phone = '8675309' 

customer = Human() 
attrs = ['name', 'phone'] 

print(customer.name) # Jenny 
print(customer.phone) # 8675309 

for a in attrs: 
    print(customer.a) # This doesn't work! 
    print(customer[a]) # Neither does this! 

我專門針對Python3（Debian的Linux的），但Python2答案將受到歡迎，以及。

Answer 1

使用getattr：

getattr(customer, a) 

---

>>> class Human: 
...  name = 'Jenny' 
...  phone = '8675309' 
... 
>>> customer = Human() 
>>> for a in ['name', 'phone']: 
...  print(getattr(customer, a)) 
... 
Jenny 
8675309
