I am writing a tkinter app in python that is a flash card quiz. It needs to be able to read from a txt file one folder ahead from the python file. In the cide you can change which file is the file loaded but this is not working even if you choose the same file. When i tried to change the file in filehandling() it broke but when it launched it worked I tried it with keywords.txt which it was already using and test.txt.
This is the file structure of the code:
from customtkinter import *from CTkMessagebox import CTkMessageboximport globimport osinformation = []file_name = 'keywords.txt'app = Nonedef hide(tk): # hides window try: tk.withdraw() except: passdef 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 informationdef changeHandler(value): global file_name file_name = value print(value) return file_namedef 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 tempdef 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") Title = CTkLabel(master=app, text="Flash Card Project", font=("Arial", 40)) PlayBtn = CTkButton(master=app, text="Start", fg_color="#005500", text_color="#000000", command=lambda: Run(app)) Changebtn = CTkButton(master=app, text="Change File", fg_color="#AA4203", text_color="#000000", command=changeFile) ExitBtn = CTkButton(master=app, text="Exit", fg_color="#550000", text_color="#000000", command=app.quit) Title.place(relx=0.5, rely=0.05, anchor="center") PlayBtn.place(relx=0.5, rely=0.4, anchor="center") Changebtn.place(relx=0.5, rely=0.5, anchor="center") ExitBtn.place(relx=0.5, rely=0.6, anchor="center") app.mainloop() exit() else: show(app) try: tk.destroy() except: passMenu()keywords.txtException in Tkinter callbackTraceback (most recent call last): File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1921, in __call__ return self.func(*args) File "C:\Users\jacen\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\customtkinter\windows\widgets\ctk_button.py", line 554, in _clicked self._command() File "E:\Documents\Python Code\Flash Cards Project\Code\test.py", line 75, in <lambda> fg_color="#550000", text_color="#000000", command=lambda: Menu(FilePicker)).place(relx=0.5, rely=0.7, anchor="center") File "E:\Documents\Python Code\Flash Cards Project\Code\test.py", line 80, in Menu information = FileHandling(file_name) File "E:\Documents\Python Code\Flash Cards Project\Code\test.py", line 27, in FileHandling with open("Text/"+filename, 'r') as f:FileNotFoundError: [Errno 2] No such file or directory: 'Text/keywords.txt'test.txtException in Tkinter callbackTraceback (most recent call last): File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1921, in __call__ return self.func(*args) File "C:\Users\jacen\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\customtkinter\windows\widgets\ctk_button.py", line 554, in _clicked self._command() File "E:\Documents\Python Code\Flash Cards Project\Code\test.py", line 75, in <lambda> fg_color="#550000", text_color="#000000", command=lambda: Menu(FilePicker)).place(relx=0.5, rely=0.7, anchor="center") File "E:\Documents\Python Code\Flash Cards Project\Code\test.py", line 80, in Menu information = FileHandling(file_name) File "E:\Documents\Python Code\Flash Cards Project\Code\test.py", line 27, in FileHandling with open("Text/"+filename, 'r') as f:FileNotFoundError: [Errno 2] No such file or directory: 'Text/test.txt'keywords.txt
