Hi Harendra,

Yes That why i used word Probably. Basically many other programmer don't know about these libraries. All libraries are common but you use when you search about them.

Let take an real example. I use Pypdf2 pdfminer. I never know about pdfplumber which excelent results.

I use urllib instead requests but request now i like the most.

You know all these that good but their others programmer who don't know about these libraries.

Cheers.
