Requirements doubt

@kunal-lonhare you can see the versions of these when you do

pip freeze

it is usual to redirect the output from this command to a requirements.txt file.

pip freeze > requirements.txt

However, I consider it bad practice to have all of the output from "pip freeze" given in the requirements.txt file because it includes the dependencies of many packages like Flask. Therefore it's a good idea to be minimalistic in the requirements.txt file and only include the primary package and allow that package to give the end-user the dependencies when he installs your package and executes

pip install -r requirements.txt

You do need the versions of the primary packages in the requirements.txt file when posting to GitHub because future releases of the package may break your code and giving the versions helps to avoid this collision.
