First of all this is probably not the simplest way to bleed all the air from a solenoid valve,
assuming a program which used it crashed before calling GPIO.cleanup().
But it works.
The question is : ...
when I pylint this code it gets the following errors:
I am not using a virtual environment or pip I don't think although one is installed.
Here is the only version of RPi.GPIO I could find.Someone said that the path for pylint is not set correctly.
This happens both running pylint in emacs and from command line.
the path is empty.
