I have this Python Tkinter code right here: from tkinter.filedialog import * import tkinter as tk class App(tk.Tk): def __init__(self): super().__init__() self.apptitle = "TODO.py" #...other code self.openfile = None self.savefile = None self.currentfile = None self.filetype = [("Text File", "*.txt"), ("Markdown File", "*.md")] #...other code def filemenu_save(self): if self.currentfile is None: self.savefile = asksaveasfile(filetypes=self.filetype, defaultextension=self.filetype) try: self.currentcontent = self.textbox.get("1.0", tk.END).rstrip("\n") with open(self.savefile.name, "w", encoding="utf-8-sig") as f: f.write(self.currentcontent) self.currentfile = self.savefile self.title(self.apptitle + " - " + self.savefile.name) except IOError as e: print("An error occurred while writing to the file:", e) else: try: self.currentcontent = self.textbox.get("1.0", tk.END).rstrip("\n") with open(self.currentfile.name, "w", encoding="utf-8-sig") as f: f.write(self.currentcontent) self.currentfile = self.currentfile except IOError as e: print("An error occurred while writing to the file:", e) #...other code That takes the content of a tk.Text() and writes it to the saved file. But, even tho this code does work on the normal Python, this didn't work in Pydroid. It gives me this error: Exception in Tkinter callback Traceback (most recent call last): File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/tkinter/__init__.py", line 2071, in __call__ return self.func(*args) ~~~~~~~~~^^^^^^^ File "/storage/emulated/0/GitHub Mobile Stuff/TODO.py/TODO.py", line 149, in filemenu_save with open(self.savefile.name, "w", encoding="utf-8-sig") as f: ^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute 'name' Even tho it should just return the file as an object and then go with the rest of the code. I'm not sure why it's not reassigning it in Pydroid. (Also I'm not that good with Python yet, there are things that I don't know of.) Continue reading...
