python - 类型错误 : Student() takes no arguments

Question

我刚开始学习 python 并收到此“TypeError:Student() takes no arguments”。有人可以帮我解决我的代码有什么问题吗？

(在 Student.py 文件中)

class Student:
    def __init_(self,name,major,gpa,is_on_probation):
        self.name = name
        self.major = major
        self.gpa = gpa
        self.is_on_probation = is_on_probation

(在 app.py 文件中)

from Student import Student

student1 = Student("Jim", "Businesss", 3.1, False)

print(student1)

Answer 1

Init 每边需要 2 个下划线:

class Student:
    def __init__(self,name,major,gpa,is_on_probation):
        self.name = name
        self.major = major
        self.gpa = gpa
        self.is_on_probation = is_on_probation
