Where I think my problem maybe in how I am running this. I want to eventually 
run from the command line. I started python idle from my linux command line 
and I was cut and pasting from my text file and seeing things work. Now i 
want to run it from the command line and its complaining. in my file I have 
something of the following.

class yes:
 def func1
  temp = re.match #####
  return str(tempREG != 'None'
        def display(self):
  print all the class attributes....
 def __init__(self,value):
  name = func1(value)
  other stuff

def func2():
 a = yes()

 print "error"
