I will come with a new tutorial till then stay tuned with SIMPLIFIED PYTHON. I hope, you found it helpful but if you have any query regarding this then feel free to ask. So guys this was all about the How To Generate QR Code With Python tutorial. Now let’s see how our QR code looks like. fill_color and back_color can change the background and the painting color of the QR, when using the default image factory. Now create an image from the QR code instance.make(fit=True) the fit parameter basically controls, if you want to automatically exhaust the QR code dimension size.add_data() method is used to add the data. Now add this data to the instance of QR code. ![]() Now we need to create a data variable to store the data.The fourth parameter is border, it controls how many boxes thick the border should be (the default is 4, which is the minimum according to the specs).The third parameter is box_size, it actually controls how many pixels each “box” of the QR code is.They should be provided as value of the error_correction property during the creation of the QR Code.ERROR_CORRECT_H: About 30% or less errors can be corrected.ERROR_CORRECT_Q: About 25% or less errors can be corrected.ERROR_CORRECT_M: (default) About 15% or less errors can be corrected. ![]()
