pylint: Fix consider-using-in

Pylint 2.11.0 extends consider-using-in check to work for
attribute access.

> To check if a variable is equal to one of many values,combine the
  values into a tuple and check if the variable is contained "in" it
  instead of checking for equality against each of the values.This
  is faster and less verbose.
