定义学生类，输入同学的数学英语计算机成绩，输出，并可以输入学号搜索信息，最后算出全班总成绩最高分和平均分

好的，以下是一个简单的Python代码示例，实现了您所需的功能：

class Student:
    def __init__(self, id, math_score, english_score, computer_score):
        self.id = id
        self.math_score = math_score
        self.english_score = english_score
        self.computer_score = computer_score
    
    def display(self):
        print("学号：", self.id)
        print("数学成绩：", self.math_score)
        print("英语成绩：", self.english_score)
        print("计算机成绩：", self.computer_score)
    
    @staticmethod
    def search(student_list, id):
        for student in student_list:
            if student.id == id:
                student.display()
                return
        print("未找到该学号的学生信息！")
    
    @staticmethod
    def get_class_score_stats(student_list):
        total_score = 0
        max_score = 0
        for student in student_list:
            total_score += student.math_score + student.english_score + student.computer_score
            max_score = max(max_score, student.math_score + student.english_score + student.computer_score)
        avg_score = total_score / len(student_list) / 3
        return max_score, avg_score


# 示例用法：
if __name__ == "__main__":
    student_list = [
        Student(1, 90, 80, 70),
        Student(2, 80, 70, 60),
        Student(3, 85, 90, 95),
    ]
    
    # 显示所有学生信息
    for student in student_list:
        student.display()
    
    # 搜索学号为2的学生信息
    Student.search(student_list, 2)
    
    # 显示全班总成绩最高分和平均分
    max_score, avg_score = Student.get_class_score_stats(student_list)
    print("全班总成绩最高分：", max_score)
    print("全班平均分：", avg_score)

需要注意的是，这只是一个简单的示例代码，实际的程序可能需要更详细的输入、输出、错误处理等机制。
