大家好，又见面了，我是你们的朋友全栈君。

学员管理系统是刚接触python时算是一个比较难的小项目，毕竟第一次接触这样的思维逻辑，不过用心学起来还是很有趣的，发现乐在其中，也就不觉得难了。下面给大家分享一下学员管理系统较为完整的代码

1.主程序

import sys ,datetime
stulist = []
stuNumlist = []
userdata = {}
while True:
    userInput = showmenu()
    if userInput == "1":
        addStu()
    elif userInput == "2":
        delStu()
    elif userInput == "3":
        revStu()
    elif userInput == "4":
        queryStu()
    elif userInput == "5":
        sys.exit()
    else:
        print("输入了错误的信息！")
        continue

2.打印菜单

def showmenu():
    print("============================================学员管理系统======================================================")
    print("#  *    *    *     *       *       *       1.添加新学员   *     *     *     *     *     *      *     *     * #")
    print("#     *     *    *     *      *         *  2.删除学员  *     *     *     *     *     *      *      *    *    #")
    print("#   *     *   *      *     *      *        3.修改学员     *     *      *     *     *     *      *      *     #")
    print("#      *      *     *      *       *       4.查询学员   *     *     *     *     *      *      *     *       *#")
    print("#   *      *     *     *      *       *    5.按Q退出系统    *     *     *     *      *      *    *      *    #")
    print("=============================================================================================================")
    userInput = input("请输入你要进行操作的操作编码：")
    return userInput

3.添加学员

def addStu():
    while True:
        user_name = input("请输入学员姓名，输入q退出:").strip().lower()
        if user_name in stulist:
            print("此学生已存在！请重新输入。")
            continue
        if len(user_name) == 0:
            print("学员姓名不能为空！")
        if user_name == "q":
            break
        user_age = input("请输入学员年龄：").strip()
        if int(user_age) < 0 or int(user_age) > 100:
            print("错误的年龄！")
            continue
        user_num = input("请输入学员学号：").strip()
        if user_num in stuNumlist:
            print("重复的学号！")
            continue
        user_sex = input("请输入学员性别[f|m]：").strip().lower()
        if user_sex != "f" and user_sex != "m":
            print("错误的性别！")
            continue
        userdata[user_name] = {"name":user_name,"age":user_age,"num":user_num,"sex":user_sex}
        userdata[user_num] = {"name":user_name,"age":user_age,"num":user_num,"sex":user_sex}
        stulist.append(user_name)
        stuNumlist.append(user_num)
        print("学员添加完成！")
        time.sleep(1.5)
        break

4.删除学员

def delStu():
    while True:
        num = 1
        for neer in stulist:
            print(num,neer)
            num += 1
        userinput = input("请选择要删除的学员编号，返回请按y，退出请按b：").strip().lower()
        if userinput == "y":
            break
        elif userinput == "b":
            sys.exit()
        elif stulist[int(userinput)-1] in stulist:
            del userdata[stulist[int(userinput)-1]]
            del userdata[stuNumlist[int(userinput)-1]]
            del stulist[int(userinput)-1]
            del stuNumlist[int(userinput)-1]
            print("删除成功！")
            time.sleep(1.5)
            break

5.修改学员信息

def revStu():
    while True:
        num = 1
        for neer in stulist:
            print(num, neer)
            num += 1
        userinput = input("请选择要修改的学员编号，返回请按y，退出请按b：").strip().lower()
        if userinput == "y":
            break
        elif userinput == "b":
            sys.exit()
        elif stulist[int(userinput) - 1] in stulist:
            user_name = input("请输入学员姓名:").strip().lower()
            if user_name in stulist:
                print("此学生已存在！请重新输入。")
                continue
            if len(user_name) == 0:
                print("学员姓名不能为空！")
            user_age = input("请输入学员年龄：").strip()
            if int(user_age) < 0 or int(user_age) > 100:
                print("错误的年龄！")
                continue
            user_num = input("请输入学员学号：").strip()
            if user_num in stuNumlist:
                print("重复的学号！")
                continue
            user_sex = input("请输入学员性别[f|m]：").strip().lower()
            if user_sex != "f" and user_sex != "m":
                print("错误的性别！")
                continue
            del userdata[stulist[int(userinput) - 1]]
            del userdata[stuNumlist[int(userinput) - 1]]
            del stulist[int(userinput) - 1]
            del stuNumlist[int(userinput) - 1]
            userdata[user_name] = {"name": user_name, "age": user_age, "num": user_num, "sex": user_sex}
            userdata[user_num] = {"name": user_name, "age": user_age, "num": user_num, "sex": user_sex}
            stulist.append(user_name)
            stuNumlist.append(user_num)
            print("学员信息修改成功！")
            time.sleep(1.5)
            break

6.查询学员信息

def queryStu():
    userinput = input("请输入查询的学员姓名或学号：").strip()
    if userinput in stuNumlist:
        name = userdata[userinput]["name"]
        age = userdata[userinput]["age"]
        num = userdata[userinput]["num"]
        sex = userdata[userinput]["sex"]
        print("学员姓名是：%s ，年龄是：%s ，性别是：%s ，性别为：%s" % (name, age, sex, num))
        time.sleep(2)
    elif userinput in stulist:
        name = userdata[userinput]["name"]
        age = userdata[userinput]["age"]
        num = userdata[userinput]["num"]
        sex = userdata[userinput]["sex"]
        print("学员姓名是：%s ，年龄是：%s ，性别是：%s ，性别为：%s" % (name, age, sex, num))
        time.sleep(2)
    elif userinput not in stuNumlist:
        print("没有该学员")
    elif userinput not in stulist:
        print("没有该学员")
