Python中实现学生管理系统的代码

学生管理系统是一个常见的小型项目，Python语言可以很好地实现这个功能。以下是一个简单的Python学生管理系统代码示例：

class Student:
    def __init__(self, name, age, gender, score):
        self.name = name
        self.age = age
        self.gender = gender
        self.score = score

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

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

    def remove_student(self, student):
        self.students.remove(student)

    def search_student(self, name):
        for student in self.students:
            if student.name == name:
                return student
        return None

    def get_students(self):
        return self.students

# 测试代码
sms = StudentManagementSystem()

s1 = Student("Tom", 18, "male", 90)
s2 = Student("Lucy", 17, "female", 85)
s3 = Student("Jack", 19, "male", 95)

sms.add_student(s1)
sms.add_student(s2)
sms.add_student(s3)

print("所有学生信息：")
for student in sms.get_students():
    print(student.name, student.age, student.gender, student.score)

search_name = "Tom"
print(f"查找学生信息: {search_name}")
search_result = sms.search_student(search_name)
if search_result:
    print(search_result.name, search_result.age, search_result.gender, search_result.score)
else:
    print(f"{search_name}不存在")

remove_name = "Lucy"
print(f"删除学生信息: {remove_name}")
remove_student = sms.search_student(remove_name)
if remove_student:
    sms.remove_student(remove_student)
    print(f"{remove_name}删除成功")
else:
    print(f"{remove_name}不存在")

以上代码定义了两个类：`Student`和`StudentManagementSystem`。`Student`类用于保存学生的信息，`StudentManagementSystem`类则负责对学生进行增删改查操作。你可以根据自己的需求进行修改和扩展。
