PyCharm enables a range of Python-linters. Some by add-in. Some by 
"External tools" 
(https://www.jetbrains.com/help/pycharm/configuring-third-party-tools.html).

Once a linter is made-available, some allow one to tune the application 
or relaxation of certain 'rules', eg whether commas in a comma-separated 
list are to be followed by a space.

Whether any enable the restriction of quotes use is another matter - 
probably for the reasons @Alan has already covered.

PyCharm auto-magically enters both an opening-quote and a closing-quote 
whenever start typing a string. The 'trick' is not to delete the close 
whilst editing.

After gaining experience, I have a convention of when to use apostrophes 
and when double-quotes. These old eyes dislike mixing both in a single 
expression - but sometimes it is the best course to follow.

YMMV!
