Django Generate Barcode With Reportlab

After Django With Barcode and Qrcode   and Django Return Pdf With Reportlab   I need something new in my Django server. I need a barcode generator for labeling stuffs.

Every code is a solution to a pratical problem. In this case I need to make the barcode labels with text for keep an inventory. The basic solution is generate a pdf/img file to print into sticker’s paper and cut it after.
