Python ModuleNotFoundError ‘requests’

To get requests one has to install requests-html. requests might already be installed.

Why did I get ModuleNotFoundError instead of ImportError? Apparently it’s new in Python 3.6 and it’s a subclass of ImportError, just more precise; catching ImportError would work for it too.
