Accept Payments with Python | Python Project for Beginners

Summary

In this tutorial, Sagar guides viewers through creating a QR code-based payment system using Python. The video covers installing required libraries, taking UPI ID input from users, and defining a payment URL. Sagar explains how to generate a unique QR code for each payment, save it as an image, and display it using the Pillow library. The tutorial is designed for beginners, with step-by-step explanations of each part of the process. Viewers will learn how to integrate QR code payments into their own applications, with practical demonstrations of generating and testing QR codes.

Takeaways

• 😀 The video explains how to generate QR codes for UPI payments using Python.
• 😀 The project involves five main steps: taking UPI ID input, defining payment URLs, generating QR codes, optionally saving them as images, and displaying them on screen.
• 😀 The script begins by importing necessary libraries such as 'qrcode' and 'Pillow' for QR code generation and display.
• 😀 The UPI ID input is taken from the user to create payment URLs for platforms like PhonePe and Paytm.
• 😀 The payment URL includes parameters like UPI ID, recipient name, amount, currency, and message for the payment request.
• 😀 QR codes are generated using the 'qrcode' library's 'make' function, which processes the payment URL into a scannable code.
• 😀 The QR codes can be saved as image files on the machine for later use or printing.
• 😀 The script also demonstrates how to display generated QR codes on screen using the 'Pillow' library's viewer function.
• 😀 The process allows for customization of the payment URLs based on the required payment platforms and parameters.
• 😀 A live demo at the end shows how the QR code works, where the user can scan it to initiate a payment through a UPI app like PhonePe or Paytm.

Q & A

What libraries are required for this project?

The required libraries are 'qrcode' for generating QR codes and 'pillow' for displaying and saving the generated QR codes as images.

How can I install the necessary libraries for this project?

You can install the libraries using the command 'pip install qrcode' for the QR code library and 'pip install pillow' for the pillow library.

What is the purpose of the QR code in this project?

The QR code is generated for each payment request. The user scans it to complete the payment, which is linked to the provided UPI ID.

What format should the payment URL follow?

The payment URL should include parameters such as the UPI ID, recipient's name, amount, currency, and an optional message. This URL is used for generating the QR code for payments.

Can I customize the payment URL parameters?

Yes, the payment URL can be customized by adjusting the parameters such as UPI ID, recipient name, amount, currency, and message as needed.

How is the payment URL generated in the script?

The payment URL is generated by defining a format string that includes the UPI ID and other payment-related details. This URL is then used to create the QR code.

What is the role of the 'input' function in the script?

The 'input' function is used to take the user's UPI ID as input, which is then used to generate the payment URL and subsequently the QR code.

Can the generated QR codes be saved as image files?

Yes, the QR codes can be saved as image files on the system using the 'save' method from the pillow library.

What happens if I skip saving the QR code as an image file?

If you skip saving the QR code as an image file, the QR code will still be displayed on the screen, and you can scan it directly without saving it to a file.

How are the QR codes displayed on the screen?

The generated QR codes are displayed on the screen using the 'show' method from the pillow library, which opens the image in a viewer.
