Too complex chained comparisons

Reports chained comparisons that can be simplified.

Example:

  def do_comparison(x):
      xmin = 10
      xmax = 100
      if x >= xmin and x <= xmax:
          pass

The IDE offers to simplify if x >= xmin and x <= xmax. When the quick-fix is applied, the code changes to:

  def do_comparison(x):
      xmin = 10
      xmax = 100
      if xmin <= x <= xmax:
          pass
