This is a preview of the video course "Generating QR Codes With Python." From restaurant e-menus to airline boarding passes, QR codes have numerous applications that impact your day-to-day life and enrich the user’s experience. In its most basic format, a QR code contains black squares and dots on a white background, with information that any smartphone or device with a dedicated QR scanner can decode. Unlike a traditional bar code, which holds information horizontally, a QR code holds the data in two dimensions, and it can hold over a hundred times more information. This is a portion of the complete course, which you can find here: https://realpython.com/courses/generating-qr-codes/ The rest of the course covers: - Change the size and margins of the QR code - Create colorful QR codes - Rotate the QR code - Replace the static background with an animated GIF
