There are lots of errors in your code

1 2 3 4 5 6

def main():     FileDialogDemo().mainloop()    if __name__ == "__main__" :     main()     sys.exit()#exits system

these are indented into class FileDialogDemo remove the indenting

---

1	self.__root.title(os.path.basement(self.__file)+"-TextEditor")

os has not been imported

---

1 2	fileName = tkinter.filedialog.askopenfilename(parent = self,                                                       filetypes = fList)

filedialog has been imported directly so tkinter. is not required in front of it

---

1 2	rook = Tk() scrollbar = Scrollbar(root)

typo rook instead of root

---

Lots of tkinter object used in the code without importing tkinter, add the following import

1	import tkinter as tk

and then add tk. in front of all the tkinter objects
