蟒蛇，如何在字符串变量分配已经与名称创建一个类的对象

Question

下面是我的代码要求：

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实现这一目标的一些见解。

Answer 1

如果你想Namedemployee由麦克唯一定义，那么你可以使用

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

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

，如果你想拥有的一个类别，定义诸如字典：

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

注：与becareful eval（）由于安全问题，请参阅Security of Python's eval() on untrusted strings?
