Python使用tkinter模块实现GUI界面的学生信息管理系统流程分步详解
Marshal_A 人气:0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_List25.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:
pass6.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):

# 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

# 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

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
