I still need to write tests and make it work with python2

[alexamici]

@lopes-gustavo you don't need to support python2, the project is python 3 only.

I like the support to read from already opened files, but I don't like the remote URL part as it requires to depend from requests that is a big dependency.

I'd suggest you to split the URL support to a different PR.

@shahramn what's your opinion?

[shahramn]

I agree with Alessandro. We want to minimise the dependencies unless they are absolutely necessary
