Python Version

[vmuriart]

Removes compatibility to versions older than 3.6 and uses some of the new features.

I didn't implement them throughout the code since it would require a few sections of the code to be refactored in order to use them to their full extent. So this is more of a preview 😄

Thanks! (As discussed in #18.)

I realized that there are probably some folks using wtf on ancient systems where there's no default Python 3.6+, or even no default Python 3.0+ (cough RHEL/CentOS 6 cough 💩).

I created a python27 branch (currently matching master), and we should add a bit of documentation explaining how to install this with Python 2.7 where needed.

what is the default version of Python in CentOS 6? Seems like it is 2.7, but i havent found anything concrete for it

Yep, that's what it is on all the ancient CentOS 6 servers which I've ever had the misfortune of using 😂. (No wait, I think one of them only had 2.6 but 💩.)

Ubuntu 16.04/xenial is the other common-but-ancient distribution which doesn't have Python 3.6+ (it has Python 3.5). I believe that everything in here except f""-strings will work with Python 3.5.

[vmuriart]

I was just about to say, that if we remove the f-strings, it can remain 3.5 compatible. And the only thing missing for 2.7 would be for them to install the backport of pathlib.
I can edit the PR to remove f-strings and add a try/except for the backport of pathlib if 2.7 users want to try to use a newer version of wtf

[DimitriPapadopoulos]

I would change python to python3 here. See #26.

[DimitriPapadopoulos]

Perhaps change or remove this sentence from the README?

It should run correctly with either Python 2.7 or 3.x.
