That's not clear. Do you mean whether x is 1 to 9 inclusive? Because 
your contrary example below suggests you mean 0 to 10 inclusive.

You might try just defining a function to do it:

  def out_of_range(x,a,b):
	# use whatever code you like

then use it as: if out_of_range(x,0,10):

But it is necessary to define exactly what is meant by it (Python ranges 
seem to exclude the upper bound). So x<0 or x>10 might not be the most 
elegant, and x is evaluated twice, but it is the clearest.
