compability changes wiht python 3

[NeelShah18]

I change seven insertion which makes it compatible with python 3. When I tried to install it in python, it is throwing me a couple of errors and I also open issue for it https://github.com/jakerylandwilliams/partitioner/issues/6#issue-375583337 here!. I did some solution for it. Hope it is helpful for others who are using python 3. Thanks for the great library.

@NeelShah18 will these changes still work for Python2?

@andyreagan It is not compatible with python2 because of urlib2 library. The reason is very simple they separate the library in python2 and python 3. But most of the companies using python3 in a development environment so i try to solve it for python3.

But I can help to make it compatible in both python2 and python3, but for that, I have to add some code and restructured the code. If the library writers are ok with it I can do that.
