Python 3.x 在python中使用类方法的程序

获取此错误：

class student:
    
    college = "tcet"
    
    def __init__(self,name,age,marks):
        self.name = name
        self.age = age
        self.marks = 90
    
    @staticmethod             #This is a  StaticMethod Decorator
    def info():
        return "This is data of students"
    
    @classmethod              #This is a  ClassMethod Decorator
    def college(cls):     
        return cls.college
        
        
s1 = student("shubham",19,100)
s2 = student("luffy",20,99.99)

print(student.college())

print(student.info())

方法只是Python中属性的另一种形式，因此当类属性

college

已经定义时，通过命名方法

college

，方法对象将替换包含字符串

的class属性
college

您可以通过简单地以不同的方式命名属性来纠正此问题：

<bound method student.college of <class '__main__.student'>>

class student:
    
    _college = "tcet"
    
    @classmethod
    def college(cls):     
        return cls._college
