QR code generator using Python

QR code generator:

This program uses the qrcode library to generate a QR code image from a given data. The generate_qr() function takes the data as input and creates a QR code instance using the qrcode.QRCode() class. It then adds the data to the QR code instance, makes the QR code and creates an image of the QR code using the make_image() method. Finally, the image is saved to a file named "qr_code.png"
