蟒蛇，如何在字符串變量分配已經與名稱創建一個類的對象

Question

下面是我的代碼要求：

Class Employee: 
    def __init__(self,age): 
     self.age= age 

main(): 

Mike = new Employee(20) 
NamedEmployee = "Mike" 

# Need some logic to refer Mike Object with value given in NamedEmployee 
string 
# example 
print(NamedEmployee.age) -- expect 20 here. 

需要如何在Python實現這一目標的一些見解。

Answer 1

如果你想Namedemployee由麥克唯一定義，那麼你可以使用

Class Employee: 
     def __init__(self,age): 
      self.age= age 

    Mike = Employee(20) 
    NamedEmployee = eval("Mike") 
    print(NamedEmployee.age) # print 20 

，如果你想擁有的一個類別，定義諸如字典：

NamedEmployee = dict() 
    NamedEmployee['Mike'] = eval("Mike") 

注：與becareful eval（）由於安全問題，請參閱Security of Python's eval() on untrusted strings?
