使用Python中的tkinter模块实现GUI界面的学生信息管理系统

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 tk

from 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)]

# [ID Name Major 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) <= 25

# 定于一个方法，用于检查班级是否规范

def is_Class(Class):

return Class.isdigit() and int(Class) > 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

# 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

Info.remove(i)

Flag = False

break

if 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

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

if len(ID) != 0 and not is_ID(ID):

Tip_Add_ID()

return

return

if len(Class) != 0 and not is_Class(Class):

return

if 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 \

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:

else:

 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")

return

if 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 True

else:

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 = 0

for line in string:

if is_Chinese(line):

count = count + 2

else:

count = count + 1

return 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window

window = 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 entry

Txt_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 entry

Txt_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 entry

Txt_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 entry

Txt_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 entry

Txt_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 entry

Txt_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
