Maybe black depends on a newer version of Python3 than 3.5.3?
I have not tried to upgrade python3.
>From https://pypi.org/project/black/ I read:
" Black can be installed by running pip install black. It requires
Python 3.6.0+ to run but you can reformat Python 2 code with it, too. "
I suggest to update the package dependency on python3.
Bye
