Using Python And Tkinter to Open, Read, and Save Text Files

How to Open, Read, and Save Text Files Using Python and Tkinter

In this Python tutorial we will create an application that allows users to open, read, and save text files using the Tkinter library for the graphical user interface. 

The application features a text editor and a menu bar for file operations, including open, save, and exit options.

What We Are Gonna Use In This Project:

- Python Programming Language.

- Tkinter for GUI.
- VS Code Editor.

Project Source Code:

import tkinter as tk

from tkinter import ttk, filedialog

class TextFile_OpenReadSave:

def __init__(self, master):

# Initialize the main application

self.master = master

master.title("Open Read Save Text File")

# Styling

master.geometry("600x400")

master.configure(bg="#f0f0f0")

# Create a Text widget for text editing

self.text_editor = tk.Text(master)

self.text_editor.pack(expand=True, fill=tk.BOTH)

# Create a menu bar

self.menubar = tk.Menu(master)

# Create a File menu in the menu bar

self.file_menu = tk.Menu(self.menubar, tearoff=0)

# Add commands to the File menu

self.file_menu.add_command(label="Open", command = self.open_file)

self.file_menu.add_command(label="Save", command = self.save_file)

self.file_menu.add_separator()

self.file_menu.add_command(label="Exit", command = master.quit)

# Add the File menu to the menu bar

self.menubar.add_cascade(label="File", menu=self.file_menu)

# Configure the menu bar for the main window

master.config(menu=self.menubar)

def open_file(self):

# Ask user to select a file for opening

file_path = filedialog.askopenfilename(filetypes=[("Text Files", "*.txt"),

        ("All Files", "*.*")])

if file_path:

# Read the contents of the selected file and insert it into the text editor

with open(file_path, "r") as file:

self.text_editor.delete("1.0", tk.END)

self.text_editor.insert(tk.END, file.read())

def save_file(self):

# Ask user to select a file for saving

file_path = filedialog.asksaveasfilename(defaultextension=".txt",

        filetypes=[("Text Files", "*.txt"),("All Files", "*.*")])

if file_path:

# Write the contents of the text editor to the selected file

with open(file_path, "w") as file:

file.write(self.text_editor.get("1.0", tk.END))

if __name__ == "__main__":

root = tk.Tk()

app = TextFile_OpenReadSave(root)

root.mainloop()
