Python '；学生'；对象没有属性'；打印详细信息'；

大家好，我的代码有问题，我不太确定哪里出了问题，我真的很感谢大家的帮助

class Student:
    def __init__(self, name, age, course, ID):
        self.name = name
        self.age = age
        self.course = course   
        self.ID = ID
def print_details(self):   
    print("Name: " + self.name)
    print("Age: " + str(self.age))         
    print("Course: " + self.course)         
    print("Student ID: " + self.ID)
student1 = Student("Bob", 20, "Computer Science", "1000121") 
student2 = Student("Alice", 21, "Computer Science", "1000475") 
student3 = Student("Jane", 18, "Information Technology", "1000823") 
student1.print_details()
student2.print_details()
student3.print_details()

因此，我得到的错误是，当试图运行代码时

“学生”对象没有“打印详细信息”属性

提前感谢

您编写的函数不在学生课堂上，请将其缩进一块

class Student:
    def __init__(self, name, age, course, ID):
        self.name = name
        self.age = age
        self.course = course   
        self.ID = ID
    def print_details(self):   
        print("Name: " + self.name)
        print("Age: " + str(self.age))         
        print("Course: " + self.course)         
        print("Student ID: " + self.ID)
student1 = Student("Bob", 20, "Computer Science", "1000121") 
student2 = Student("Alice", 21, "Computer Science", "1000475") 
student3 = Student("Jane", 18, "Information Technology", "1000823") 
student1.print_details()
student2.print_details()
student3.print_details()

print\u details（）

方法在类之外。常见缩进错误。修复代码中的缩进。该功能应为内部一级。它应该在课堂上@michale谢谢你我对这一切都是新手，还在学习
