Since I am comparatively better in Django than in React and I more into backend development, I actually build my DAPPs in Django.
(You can see them here - https://github.com/zaryab2000)

Therefore , through my projects I work with both web3.py ( for reading data from the contracts.) And web3.js for making transactions using Metamask extension.

Although my DAPPs really fine. However I don't see this practice of integrating Django with blockchain more popular?

I want to know if it's okay for me to develop such DAPPs or is it compulsory to learn REACT like majority of them do.
