How to Use Tkinter to Choose a Folder for Saving Files in Python

When working with file handling in Python, it's often beneficial to allow users to choose where they want to save their files. This makes your application flexible and user-friendly. In this guide, we will explore how to use Tkinter, the standard GUI toolkit for Python, to open a dialog box that lets users select a folder before saving a file.

Problem Statement

Imagine you’re building a program that performs a series of calculations and you want to store the results in a text file. Instead of hardcoding a file path, allowing users to choose their desired save location enhances usability. Our goal is to:

Prompt the user for two numbers to add.

Repeatedly perform the addition for a maximum of three attempts.

Let the user select a folder on their computer to save the results in a file named results.txt.

Step-by-Step Solution

To implement this, we will incorporate Tkinter's filedialog module. Below are the organized steps for achieving this:

Step 1: Import Necessary Modules

Begin by importing the required modules:

Step 2: Create a Tkinter Root Window

You need to create a root window for Tkinter. However, since we don't want it to appear on the screen, we will hide it immediately:

Step 3: Define the Function for Addition and File Saving

Next, define the main function where the addition and file saving will take place. Here’s how you could write this function:
