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。")continueif len(user_name) == 0:print("学员姓名不能为空！")if user_name == "q":breakuser_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！")continueuser_num = input("请输入学员学号：").strip()if user_num in stuNumlist:print("重复的学号！")continueuser_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！")continueuserdata[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 = 1for neer in stulist:print(num,neer)num += 1userinput = 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":breakelif 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 = 1for neer in stulist:print(num, neer)num += 1userinput = 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":breakelif 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。")continueif 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！")continueuser_num = input("请输入学员学号：").strip()if user_num in stuNumlist:print("重复的学号！")continueuser_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！")continuedel 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")
