If the above code shows an image error, then you have to write on the top import Image and install its package by moving a cursor on the red bulb. After installing the package, remove it from the top and above code works and save your image in the path where you have created the Python Project in windows as shown below.
Now scan the QR Code, it connects you to the Gk Scientist as shown below.
(5) Generate a Coloured QR Code:
Write the following code as shown below.
Now the Qr Code image is saved in the path where you have created the Python Project as shown below.
Now scan the QR Code, it connects you to the Gk Scientist as shown below.
