### Reading and Generating QR codes in Python Using QRtools
-QR code, or quick response code, is a trademark for a type of 2 dimensional barcode.
-2 dimensional barcodes are similar to one dimensional barcodes, but can store more information per unit area.
# Generate a QR Code
-qrtools contains a class QR (can be viewed in the source code),
-for which we must initially create an object.
-The object takes the following arguments
1-> data
2-> pixel_size
3-> level
4-> margin_size
5-> data_type
