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.
