Should be okay to merge once failing builds go green.

@navinkarkera CI seems to be failing due to codecov issues, can you kindly check if you can bump it's version to get the CI running?

[navinkarkera]

@tecoholic codecov has been removed from pypi. I have removed it and fixed CI in #10 .

[tecoholic]

@navinkarkera I see. Thank you.

[sameenfatima78]

@navinkarkera Can you rebase your PR so the failures are fixed?
