How can i open a text file on a Notepad made in python?
Question:
I’m trying to add a function that allows me to open a text file on a notepad built in python but this error shows up TypeError: expected str, bytes or os.PathLike object, not list
I’m actually really new to programming and i’m following this tutorial about how to make a notepad on python, i’ve tried importing os but i had no idea how to use it. Thanks in advance

Answers:
The error gives you a hint at what’s happening.
You are getting this error: TypeError: expected str, bytes or os.PathLike object, not list
This suggests that this line:
file = open(file,"r+")
is trying to open a list. Why might that be? Well, the function you are using here to assign the file variable is returning a list of files not a single filename:
file = filedialog.askopenfiles(parent=root, mode='r+', title="Select a file")
Is there a chance you misread the tutorial and you should have written:
file = filedialog.askopenfilename(parent=root, mode='r+', title="Select a file")
Check out the subtle difference between the two functions here: http://epydoc.sourceforge.net/stdlib/tkFileDialog-module.html#askopenfiles.
I made a similar app without GUI but it is the same at the core. Instead of the text entering stuff in tkinter i used standard input function in console. Here’s my readable code:
(Look at my read function)
print('My NoteBook')
print('Note: Do not reuse file names for text will be overwritten.')
import sys
import replit
exit=0
while exit!='y':
m=input('Select an option: a)read your docs or b)write a doc or c)delete a doc ')
def writes():
title=input('Enter the title of this paper: ')
textstuff = input('Write something: ')
text_file = open(title,'w')
text_file.write(textstuff)
text_file.close()
def read():
inputFileName = input("Enter name of paper: ")
inputFile = open(inputFileName, "r")
for line in inputFile:
sys.stdout.write(line)
def delete():
import os
print("Enter the Name of Paper: ")
filename = input()
os.remove(filename)
print("nPaper deleted successfully!")
if m=='a':
read()
elif m=="b":
writes()
else:
delete()
exit=input('nDo you want to exit, y/n ')
replit.clear()
sys.exit('Thank you' )
I made an example of a text editor with tkinter.
You can look at the reading function.
