用Python写一个学生管理项目，该项目是通过面向对象的方法设计学生类Student，包含一个学生编号(No)、学生姓名(Name)性别(Sex)、年龄(Age)，然后设计学生记录管理类StudentList来管理一组学生记录，并且控制台输入1显示所有学生信息，输入2增加一个学生，输入3删除学生信息，输入4更新学生信息，输入5退出系统。然后显示所有学生的时候按表格输出

好的，我可以帮你写一个简单的学生管理项目，以下是代码：

class Student:
    def __init__(self, No, Name, Sex, Age):
        self.No = No
        self.Name = Name
        self.Sex = Sex
        self.Age = Age

class StudentList:
    def __init__(self):
        self.students = []

    def add_student(self, No, Name, Sex, Age):
        student = Student(No, Name, Sex, Age)
        self.students.append(student)

    def delete_student(self, No):
        for student in self.students:
            if student.No == No:
                self.students.remove(student)
                return True
        return False

    def update_student(self, No, Name, Sex, Age):
        for student in self.students:
            if student.No == No:
                student.Name = Name
                student.Sex = Sex
                student.Age = Age
                return True
        return False

    def show_students(self):
        print("{:<10}{:<10}{:<10}{:<10}".format("No", "Name", "Sex", "Age"))
        for student in self.students:
            print("{:<10}{:<10}{:<10}{:<10}".format(student.No, student.Name, student.Sex, student.Age))

def main():
    student_list = StudentList()
    while True:
        print("1. Show all students")
        print("2. Add a student")
        print("3. Delete a student")
        print("4. Update a student")
        print("5. Exit")
        choice = input("Please enter your choice (1-5): ")
        if choice == "1":
            student_list.show_students()
        elif choice == "2":
            No = input("Please enter student No: ")
            Name = input("Please enter student Name: ")
            Sex = input("Please enter student Sex: ")
            Age = input("Please enter student Age: ")
            student_list.add_student(No, Name, Sex, Age)
        elif choice == "3":
            No = input("Please enter student No: ")
            if student_list.delete_student(No):
                print("Delete successfully!")
            else:
                print("No such student!")
        elif choice == "4":
            No = input("Please enter student No: ")
            Name = input("Please enter student Name: ")
            Sex = input("Please enter student Sex: ")
            Age = input("Please enter student Age: ")
            if student_list.update_student(No, Name, Sex, Age):
                print("Update successfully!")
            else:
                print("No such student!")
        elif choice == "5":
            break
        else:
            print("Invalid input, please try again.")

if __name__ == "__main__":
    main()

你可以在控制台中运行该程序，根据提示输入相应的操作选项进行学生信息管理。当选择显示所有学生信息时，输出的格式为表格形式。
