You can generate QR codes in Python by using the qrcode
library. Here is a simple example code to generate a QR code image:
import qrcode
# create QR code instance
qr = qrcode.QRCode(version=1, box_size=10, border=4)
# add data to the QR code
data = "https://example.com"
qr.add_data(data)
qr.make(fit=True)
# create an image from the QR code
img = qr.make_image(fill_color="black", back_color="white")
# save the image as a PNG file
img.save("example.png")
In this example, we first import the qrcode
library. We then create a QR code instance with the desired size and border using the QRCode
class. Next, we add the data to the QR code using the add_data
method and make the QR code using the make
method. Finally, we create an image from the QR code using the make_image
method and save the image as a PNG file using the save
method.
You can customize the QR code’s appearance by adjusting the fill_color
and back_color
parameters of the make_image
method.
