Editor to share with you how to use python to generate QR code, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Generate a QR code

QR code is also called 2D barcode. The common QR code is the full name Quick Response of QR Code,QR, which is a very popular coding method on mobile devices in recent years, and it is very easy to generate a QR code. In Python, we can generate a QR code through the MyQR module, while we only need 2 lines of code to generate a QR code. We first install the MyQR module. Here we choose the domestic source to download:

Pip install qrcode

After the installation is complete, we can start writing code:

Import qrcodetext = input (enter text or URL:) # set URL must add http://img = qrcode.make (text) img.save () # Save the picture to the local directory, you can set the path img.show ()

After we execute the code, we will generate a QR code under the project. Of course, we can also enrich the QR code:

Let's install the MyQR module first

Pip install myqrdef gakki_code (): version, level, qr_name = myqr.run (words= https://520mg.com/it/#/main/2, # can be a string or URL (preceded by http (s): / /) version=1, # set fault tolerance to the highest level='H', # control error correction level, with the range of L, M, Q, H. Increase the picture=gakki.gif from left to right, # combine the QR code and the picture into colorized=True, # the color QR code contrast=1.0, # to adjust the contrast of the picture, 1. 0 represents the original picture, a smaller value indicates lower contrast, and vice versa. The default is 1.0 brightness=1.0. # is used to adjust the brightness of the picture. The other usage and values are the same as the above save_name=gakki_code.gif. # saves the name of the file. The format can be jpg,png,bmp,gif save_dir=os.getcwd () # control location) gakki_code ()

In addition, MyQR also supports dynamic pictures.
