我正在用python写一个tkinter应用程序，它是一个闪存卡测验.它需要能够从python文件前面的一个文件夹中读取txt文件.在cide中，您可以更改加载的文件，但即使您 Select 相同的文件，这也不起作用.当我试图在filehandling()中更改文件时，它坏了，但当它启动时，它工作了，我用它已经在使用的keywords.txt和Test.txttry 了它.
以下是代码的文件 struct :
from customtkinter import *
from CTkMessagebox import CTkMessagebox
import glob
import os
information = []
file_name = 'keywords.txt'
app = None
def hide(tk):
# hides window
try:
tk.withdraw()
except:
pass
def show(tk):
# shows window
tk.deiconify()
def FileHandling(filename):
# file handling
information = []
with open("Text/"+filename, 'r') as f:
temp = f.read().split("\n")
for i in range(0, len(temp), 2):
temp_list = []
# makes 2d array
temp_list.append(temp[i].capitalize())
temp_list.append(temp[i+1].capitalize())
information.append(temp_list)
return information
def changeHandler(value):
global file_name
file_name = value
print(value)
return file_name
def changeFile():
# add change file code here
files = getFiles()
filePicker(files)
def getFiles():
temp = []
os.chdir("../Code/Text")
for file in glob.glob("*.txt"):
temp.append(file)
return temp
def filePicker(files):
hide(app)
FilePicker = CTkToplevel()
FilePicker.geometry("500x400")
FilePicker.resizable(False, False)
FilePicker.title("FIle Picker")
Title = CTkLabel(
master=FilePicker, text="Which file would you like to load?", font=("Arial", 10))
Title.place(relx=0.5, rely=0.05, anchor="center")
Options = CTkComboBox(FilePicker, values=files,
variable="Unselected", command=changeHandler) # type: ignore
Options.place(relx=0.5, rely=0.5, anchor="center")
ExitBtn = CTkButton(master=FilePicker, text="Menu",
fg_color="#550000", text_color="#000000", command=lambda: Menu(FilePicker)).place(relx=0.5, rely=0.7, anchor="center")
def Menu(tk=None):
global information
information = FileHandling(file_name)
global app
# makes app unless app is made then it reveals it.
if app == None:
app = CTk()
app.geometry("500x400+750+300")
app.resizable(False, False)
app.title("Menu")
set_appearance_mode("dark")

ExitBtn.place(relx=0.5, rely=0.6, anchor="center")
app.mainloop()
exit()
