Update payment.py #93
Description
The Tkinter code was refined to include a process_payment function that validates and submits essential payment details only when all required fields are filled. A confirmation message was added using messagebox.showinfo to display a summary of the entered details upon successful submission. A clear_entries function ensures all input fields are reset post-submission, enhancing usability. Visual improvements like consistent fonts, organized layout using frames, and subtle padding adjustments were made for better aesthetics and usability, optimizing the payment process in the application.
