Python Frameworks and Libraries

Django is the most popular framework among Python developers. No surprise here, seeing how Web development is so popular among Python users. Interestingly, 43% of respondents are using IPython, which clearly shows it’s being used not only for scientific purposes, but for general software development as well.

A large number of respondents also specified Flask as their framework of choice.

Hi folks,

For all you who have been here for a long time, you probably noticed that after certain period of inactivity, this channel started posting content again. First owner of this channel (a friend of mine, admin of AI India), didn't have enough time to take care of it so he transferred ownership to me. I am 27 year old software engineer, living in Europe, owner and founder of @bigdataspecialist channel (and many more, i will add them in comment if somebody is interested into checking them).

I started posting interactive content, with one of my employees helping me with it since i don't have too much free time. I really hope you like it 😉

I would like to inform you that we are having giveaway tomorrow in my main channel (@bigdataspecialist). We are buying you paid course of your choice. Check last post in that channel for more info.

That's it, I really hope you like the new content, feel free to reach me out if you need anything and also write any suggestions what would you like to see in this or other channel of mine in comments. Thank you all and have a nice day.
