开发工具：Pycharm2021以上，IDLE 创建一个学校管理系统，包括学校类、教师类、学生类和课程类。输入学生信息，老师信息，课程信息，能够对应进行打印。

在Python中，使用PyCharm 2021及以上版本和标准的IDLE作为开发环境，你可以开始构建一个简单的学校管理系统。我们将创建四个主要类：School（学校）、Teacher（教师）、Student（学生）和Course（课程）。这里是一个基本的设计和实现示例：

class School:
    def __init__(self):
        self.teachers = []
        self.students = []
        self.courses = []

    def add_teacher(self, teacher):
        self.teachers.append(teacher)

    def add_student(self, student):
        self.students.append(student)

    def add_course(self, course):
        self.courses.append(course)

    def print_info(self):
        print("School Information:")
        for teacher in self.teachers:
            teacher.print_info()
        for student in self.students:
            student.print_info()
        for course in self.courses:
            course.print_info()

class Teacher:
    def __init__(self, name, subject):
        self.name = name
        self.subject = subject

    def print_info(self):
        print(f"Teacher: {self.name}, Subject: {self.subject}")

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

    def print_info(self):
        print(f"Student: {self.name}, Grade: {self.grade}, Major: {self.major}")

class Course:
    def __init__(self, title, teacher):
        self.title = title
        self.teacher = teacher

    def print_info(self):
        print(f"Course: {self.title}, Taught by: {self.teacher.name}")

# 示例
mr_smith = Teacher("Mr. Smith", "Math")
student_john = Student("John Doe", 10, "Mathematics")
course_algebra = Course("Algebra", mr_smith)

school = School()
school.add_teacher(mr_smith)
school.add_student(student_john)
school.add_course(course_algebra)
school.print_info()

在这个例子中，用户可以创建教师、学生和课程实例，并将它们添加到学校中。`print_info()`方法用于显示每个类的信息。如果你想继续扩展这个系统，你可以考虑添加更多的功能，比如注册、选课、成绩管理等。
