f strings are not supported with Python 3.5

[scottlinuxden]

There are numerous f strings in folder.py, errors.py, and list.py that causing issues when the package imports. Those need changed to "*".format(var1, var2) calls moving forward. I changed those and shareplum now imports correctly.

Shareplum requires Python 3.6+. See https://github.com/jasonrollins/shareplum/blob/master/setup.py

Python 3.5 will not receive any more security updates starting next month, I suggest you upgrade.

Sad there is no retro compatibility within the same major python version.

If don't want to break your system (if you use stretch or older — see debian rules "Don't suffer shiny new stuff"); it is better to install python3.6 or later from the tarball in virtual env.

For others, a patch similar of what you did:
