Python Tkinter 文本小部件不显示 .txt 文件中的内容

Question

I am currently creating a Python Tkinter program to edit and create.txt files. In doing so, I have created a file opening system using the File Dialog method and have the user selected path saved as: a file variable. I have looped through the file and added it to the text widget via the insert method. I opened a test.txt file with a 2 line content. It simply says: this is a test file. (New line) it is used for test purposes

The problem is that the text widget appears blank

My code is:

from tkinter import *
from tkinter import FileDialog
master = Tk()

#all other code like filedialog opening code is here

editarea = Text(master,height=10,width=25)
editarea.grid(column=0,row=1)
f = open(file,"r")
for x in f:
    editarea.insert(END,x)

This code is run in Python 3.7

How do I make the Text widget display the contents of the.txt file and can still be edited?

Many Thanks (For the future)

I am aware the code above is a bit vage and won't run but you hopefully get the gist of my problem:)

Answer 1

here is a better solution, whole file at once

with open(file, "r") as txtr:
    data = txtr.read()
editarea.insert(END, data)

this here is line by line

with open(file, "r") as txtr:
    data = txtr.readlines()
for x in data:
    editarea.insert(END, x)

if for some strange reason it didn't work, try this:

for x in range(len(data)):
    editarea.insert(END, data[x])
