Change Files's Extension Using Python Scripts

I write this Python file to do the process of changing many of files's extension instead of renaming each of them which is very time-consuming and boring. You can change the files extension by running this script and following these simple steps below:

• Choose your destination folder containing your files
• Fill in the current files's extension
• Click Scan Files to see the current number of files in the directory
• Fill in your extension you want to change to in the next text box
• And finally click Convert!

Libraries I used in this file:

• tkinter : I use tkinter to make the GUI and make the app visible and easier to use.
• glob : glob library helps me to define the extension-type files in the directory and scan them.
• os : This library helps me to interact with the operating system (choose and change the current working directory and rename files).

Note:

I hit some problems with the convesion to exe file. I tried using converter from google search results but there are still some errors and I cannot run the converted exe file. If you have any solution to my problem, please contact me. Thank you very much.
