Hi all!

Every person is using barcodes nowadays, mostly without noticing this. When we are buying the groceries in the store, their identifiers are getting from barcodes. Its also the same with goods in the warehouses, postal parcels and so on. But not so many people actually know, how it works.

Today I will try to answer the following question: "What if we use Python instead of PHP?".

I have asked this question myself many times. I have been using PHP for 11 years already and am a certified PHP specialist. I have mastered it so it works just the way I want.
