本文只有代码，介绍了有关GUI界面的学生信息管理系统的实现。

已经过调试没有很大问题。
如有错误，还请批评指正。

1.导入tkinter模块

import tkinter as tkfrom tkinter import messagebox

2.定义一个全局变量储存学生信息

# 用来存储学生信息的总列表[学号(6位)、姓名、专业、年龄(17~25)、班级(序号)、电话(11位)]#[IDNameMajor Age Class Telephone]Info = []

3.为了使学生信息的数据持久化，可以将信息写入文件此处命名为’Student_Info.txt’

# 定义一个方法用于使用w模式写入文件：传入已经存好变更好信息的列表，然后遍历写入txt文档def WriteTxt_w_Mode(Student_List):# w:只写入模式，文件不存在则建立，将文件里边的内容先删除再写入with open("Student_Info.txt","w",encoding="utf-8") as f:for i in range(0,len(Student_List)):Info_dict = Student_List[i]# 最后一行不写入换行符'\n'if i == len(Student_List) - 1:f.write("{0}\t{1}\t{2}\t{3}\t{4}\t{5}".format \(Info_dict["ID"],Info_dict["Name"],Info_dict["Major"],Info_dict["Age"],Info_dict["Class"],Info_dict["Telephone"]))else:f.write("{0}\t{1}\t{2}\t{3}\t{4}\t{5}\n".format \(Info_dict["ID"],Info_dict["Name"],Info_dict["Major"],Info_dict["Age"],Info_dict["Class"],Info_dict["Telephone"]))

4.读取保存的文件信息

# 定义一个方法用于读取文件def ReadTxt() -> list:# 临时列表Temp_List1 = []Temp_List2 = []# 打开同目录下的文件f = open("./Student_Info.txt",'r', encoding="utf-8")# 遍历，读取文件每一行信息for i in f:a = str(i)b = a.replace('\n', '')Temp_List1.append(b.split("\t"))# 将读写的信息并入临时列表while len(Temp_List2) < len(Temp_List1):for j in range(0,len(Temp_List1)):ID = Temp_List1[j][0]Name = Temp_List1[j][1]Major = Temp_List1[j][2]Age = Temp_List1[j][3]Class = Temp_List1[j][4]Telephone = Temp_List1[j][5]Info_dict = {"ID":ID, "Name":Name, "Major":Major, "Age":Age, "Class":Class, "Telephone":Telephone }Temp_List2.append(Info_dict)# 关闭文件f.close()# 将含有学生信息的临时列表返回return Temp_List2

5.为了使每次运行程序可以使用保存的学生信息，将文件信息导入到全局变量里

# 用于将文件里的信息存入全局变量Info中try:for i in ReadTxt():Info.append(i)except:pass

6.用一系列方法检查输入是否规范

# 定于一个方法，用于检查学号是否规范def is_ID(ID):return len(ID) == 6 and ID.isdigit()# 定于一个方法，用于检查年龄是否规范def is_Age(Age):return Age.isdigit() and 17 <= int(Age) and int(Age)  0# 定于一个方法，用于检查电话是否规范def is_Telephone(Telephone):return len(Telephone) == 11 and Telephone.isdigit()

7.完成相关操作后将有提示信息

# 提示信息def Tip_Add():messagebox.showinfo("提示信息","添加成功")def Tip_Search():messagebox.showinfo("提示信息","查询成功")def Tip_Del():messagebox.showinfo("提示信息","删除成功")def Tip_Mod():messagebox.showinfo("提示信息","修改成功")def Tip_Add_ID_Repeat():messagebox.showinfo("提示信息","此学号已经存在，请勿重复添加！")def Tip_Del_ID_None():messagebox.showinfo("提示信息","此学号不存在，请重新输入！")def Tip_Search_None():messagebox.showinfo("提示信息","未查询到有关学生信息！")def Tip_Add_ID():messagebox.showinfo("提示信息","学号格式有误，请重新输入！")def Tip_Add_Age():messagebox.showinfo("提示信息","年龄格式有误，请重新输入！")def Tip_Add_Class():messagebox.showinfo("提示信息","班级格式有误，请重新输入！")def Tip_Add_Telephone():messagebox.showinfo("提示信息","电话格式有误，请重新输入！")

8.添加学生信息的主方法

# 1.添加学生信息的主方法def Add_Student_Info(ID, Name, Major, Age, Class, Telephone):# 导入信息global Info# 检查输入信息是否规范if not is_ID(ID):Tip_Add_ID()returnfor i in Info:if ID == i['ID']:Tip_Add_ID_Repeat()returnif not is_Age(Age):Tip_Add_Age()returnif not is_Class(Class):Tip_Add_Class()returnif not is_Telephone(Telephone):Tip_Add_Telephone()return# 用字典整合学生信息Info_dict = {'ID':ID, 'Name':Name, 'Major':Major, 'Age':Age, 'Class':Class, 'Telephone':Telephone}# 将字典存入总列表Info.append(Info_dict)# 添加成功Tip_Add()# 将信息写入文件WriteTxt_w_Mode(Info)

9.删除学生信息的主方法

# 2.删除学生信息的主方法def Del_Student_Info(ID):# 检查输入信息是否规范if not is_ID(ID):Tip_Add_ID()return# 用于指示是否删除的状态指标Flag = True# 导入信息global Info# 遍历，删除学生信息for i in Info:if ID == i["ID"]:Info.remove(i)Flag = Falsebreakif Flag:Tip_Del_ID_None()return# 删除成功Tip_Del()# 将删除后的信息写入文件WriteTxt_w_Mode(Info)

10.打开修改学生信息窗口的方法

# 3.修改学生信息，ID符合条件则打开修改学生信息的窗口def Mod_Student_Info(ID):if not is_ID(ID):Tip_Add_ID()return# 用于指示是否打开窗口的指标Flag = Trueglobal Infofor i in Info:if ID == i["ID"]:Window_Mod_Input(ID)Flag = Falsebreakif Flag:Tip_Del_ID_None()return

11.修改学生信息的主方法

# 3.修改学生信息的主方法def Mod_Student_Info_1(ID, Name, Major, Age, Class, Telephone):# 检查输入信息是否规范if not is_ID(ID):Tip_Add_ID()returnif not is_Age(Age):Tip_Add_Age()returnif not is_Class(Class):Tip_Add_Class()returnif not is_Telephone(Telephone):Tip_Add_Telephone()return# 导入信息global Info# 遍历，修改学生信息for i in Info:if i["ID"] == ID:i["Name"] = Namei["Major"] = Majori["Age"] = Agei["Class"] = Classi["Telephone"] = Telephone# 修改成功Tip_Mod()# 将修改后的信息写入文件WriteTxt_w_Mode(Info)

12.查找学生信息的主方法

# 4.查找学生信息的主方法def Search_Student_Info(ID, Name, Major, Age, Class, Telephone):# 检查输入是否规范，规范的和空字符串通过if len(ID) != 0 and not is_ID(ID):Tip_Add_ID()returnif len(Age) != 0 and not is_Age(Age):Tip_Add_Age()returnif len(Class) != 0 and not is_Class(Class):Tip_Add_Class()returnif len(Telephone) != 0 and not is_Telephone(Telephone):Tip_Add_Telephone()return# 导入信息global Info# 临时列表List = []# 用来指示是否查找到学生的信息指标Flag = False# 遍历，根据输入的部分信息找到符合条件的学生for i in Info:if (i["ID"]==ID or len(ID)==0)and \(i["Name"]==Name or len(Name)==0)and \(i["Major"]==Major or len(Major)==0)and \(i["Age"]==Age or len(Age)==0)and \(i["Class"]==Class or len(Class)==0)and \(i["Telephone"]==Telephone or len(Telephone)==0)and \(len(ID)!=0 or len(Name)!=0 or len(Major)!=0 or len(Age)!=0 or len(Class)!=0 or len(Telephone)!=0 ):List.append(i)if len(List) != 0:Flag = True# 在主界面打印符合条件学生信息Print_Student_Info(List)# 是否查找成功if Flag:Tip_Search()else:Tip_Search_None()

13.显示所有学生信息的主方法

# 5.显示所有学生的主方法def Print_Student_Info(Student_Info):# 定义一个字符串用于存储想要输出显示的内容str_out = ""# 学生信息为空将返回if Student_Info is None:result.set("学生信息为空")returnif len(Student_Info) == 0:result.set("无学生信息")return# 学生信息不为空if len(Student_Info) != 0:str_out += "学生信息如下：\n"# 显示信息标题str_out += ("{:^7}".format("学生学号") +"{:^7}".format("学生姓名") +"{:^7}".format("学生专业") +"{:^7}".format("学生年龄") +"{:^5}".format("班级") +"{:^9}".format("电话号码") +"\n")for i in range(0, len(Student_Info)):# 格式化字符串str_out += ("{:^}".format(Student_Info[i].get("ID")) + ' '*(11-Len_Str(Student_Info[i].get("ID"))) +"{:^}".format(Student_Info[i].get("Name")) +' '*(11-Len_Str(Student_Info[i].get("Name")))+"{:^}".format(Student_Info[i].get("Major")) +' '*(13-Len_Str(Student_Info[i].get("Major")))+"{:^}".format(Student_Info[i].get("Age")) +' '*(10-Len_Str(Student_Info[i].get("Age")))+"{:^}".format(Student_Info[i].get("Class")) +' '*(5-Len_Str(Student_Info[i].get("Class")))+"{:^}".format(Student_Info[i].get("Telephone")) +' '*(11-Len_Str(Student_Info[i].get("Telephone")))+"\n")# 在主界面显示学生信息result.set(str_out)

13.1 问题一：格式化字符排版问题

>>>在字符串长度的计算中，中文和西文的字符串长度不一致，这会导致排版出错<<<

解决方法一：可以自定义字符串计算函数，用西文空格填补

# 定义一个方法，用于判断是否为中文字符def is_Chinese(ch):if ch >= '\u4e00' and ch <='\u9fa5':return Trueelse:return False# 定义一个方法，用于计算中西文混合字符串的字符串长度def Len_Str(string):count = 0for line in string:if is_Chinese(line):count = count + 2else:count = count + 1return count

解决方法二：如果只是纯中文文本，可以用chr(12288)，用中文空格填补（但在中西文混合的字符串仍然会出现排版不齐的情况）

14.添加学生信息的窗口

# 添加学生信息的窗口def Window_Add():# 实例化对象，创建root的子窗口windowwindow = tk.Toplevel(root)# 窗口名字window.title("添加学生信息")# 窗口大小window.geometry('500x500')# 关于学号的 label 和 entryTxt_ID = tk.StringVar()Txt_ID.set("")Label_Line1 = tk.Label(window, text = "学 号 (6 位)：", font = ('Arial', 10), width = 15).place(x = 75, y = 50, anchor = 'nw')Entry_Line1 = tk.Entry(window, show = None, font = ('宋体', 15), textvariable = Txt_ID, width = 20)Entry_Line1.place(x = 200, y = 50, anchor = 'nw')# 关于姓名的 label 和 entryTxt_Name = tk.StringVar()Txt_Name.set("")Label_Line2 = tk.Label(window, text = "姓 名：", font = ('Arial', 10), width = 15).place(x = 75, y = 100, anchor = 'nw')Entry_Line2 = tk.Entry(window, show = None, font = ('宋体', 15), textvariable = Txt_Name, width = 20)Entry_Line2.place(x = 200, y = 100, anchor = 'nw')# 关于专业的 label 和 entryTxt_Major = tk.StringVar()Txt_Major.set("")Label_Line3 = tk.Label(window, text = "专 业：", font = ('Arial', 10), width = 15).place(x = 75, y = 150, anchor = 'nw')Entry_Line3 = tk.Entry(window, show = None, font = ('宋体', 15), textvariable = Txt_Major, width = 20)Entry_Line3.place(x = 200, y = 150, anchor = 'nw')# 关于年龄的 label 和 entryTxt_Age = tk.StringVar()Txt_Age.set("")Label_Line4 = tk.Label(window, text = "年 龄 (17~21)：", font = ('Arial', 10), width = 15).place(x = 75, y = 200, anchor = 'nw')Entry_Line4 = tk.Entry(window, show = None, font = ('宋体', 15), textvariable = Txt_Age, width = 20)Entry_Line4.place(x = 200, y = 200, anchor = 'nw')# 关于班级的 label 和 entryTxt_Class = tk.StringVar()Txt_Class.set("")Label_Line5 = tk.Label(window, text = "班 级 (序号)：", font = ('Arial', 10), width = 15).place(x = 75, y = 250, anchor = 'nw')Entry_Line5 = tk.Entry(window, show = None, font = ('宋体', 15), textvariable = Txt_Class, width = 20)Entry_Line5.place(x = 200, y = 250, anchor = 'nw')# 关于电话的 label 和 entryTxt_Telephone = tk.StringVar()Txt_Telephone.set("")Label_Line6 = tk.Label(window, text = "电 话 (11位)：", font = ('Arial', 10), width = 15).place(x = 75, y = 300, anchor = 'nw')Entry_Line6 = tk.Entry(window, show = None, font = ('宋体', 15), textvariable = Txt_Telephone, width = 20)Entry_Line6.place(x = 200, y = 300, anchor = 'nw')# 关于"确认"组件，此处绑定函数Add_Student_Info用于添加学生信息Button1_Yes = tk.Button(window, text = '确认', bg = 'silver', font = ('Arial', 12), command = lambda:Add_Student_Info(Txt_ID.get(), Txt_Name.get(), Txt_Major.get(),Txt_Age.get(),Txt_Class.get(),Txt_Telephone.get()), width = 10)Button1_Yes.place(x = 75, y = 400, anchor = 'nw')# 关于"取消"组件，此处绑定函数destroy()用于关闭窗口Button2_No = tk.Button(window, text = '取消', bg = 'silver', font = ('Arial', 12), command = lambda:window.destroy(), width = 10)Button2_No.place(x = 325, y = 400, anchor = 'nw')# 窗口显示window.mainloop()

14.1 问题二：不能读取到输入框内容

>>> 在使用get()函数时，如Txt_ID.get()不能读取到输入框的内容

解决方法:创立窗口时定义为主窗口的子窗口，如果为window=tk.TK()，将运行错误

window = tk.Toplevel(root)

14.2 问题三： Tk.Button中command指令无法执行有传参的函数

>>>在Button中使用command时，如果绑定的方法有参数的传递，不能写成这样：

command = func(int a, int b)

>>> 如果写成这样，那么在调试时会直接执行，即不用点击按钮就执行

解决方法：使用lambda

15.删除学生信息的窗口
