请纠正我。 我写的代码在笔记本里

Question

class Student:
    workshop = 'python'
    def _init_(self, name, age):
        self.name = name
        self.age = age
    def describe(self):
        print(self.name,"is",self.age,"years old and participating in",
              Student.workshop,"class")
        return

student1 = Student("Sridhar", 35 )
student1.name   

Answer 1

init方法需要两个下划线__ 。 因此，

改变这个：

def _init_(self, name, age):

对此：

def __init__(self, name, age):

所以：

class Student:
    workshop = 'python'
    def __init__(self, name, age):
        self.name = name
        self.age = age
    def describe(self):
        print(self.name,"is",self.age,"years old and participating in",
              Student.workshop,"class")
        return

student1 = Student("Sridhar", 35)
print(student1.name)
student1.describe()

OUTPUT：

Sridhar
Sridhar is 35 years old and participating in python class
