this is not clear.  Are you trying to have a timer so that your program d=
oes=20
something on certain intervals?

you used re.match() which searches for the regex at the beginning of the=20
string.  It is basically for when the string is expected to exactly match=
 the=20
regex.  What you want is re.search, it is used the same way just a differ=
ent=20
function name.

words =3D string.split(sentence)
for word in words:
   if re.match(r"\w+"):
       print "I am a valid python variable name"

is the type of logic where match makes sense.  Basically think of match a=
s the=20
equivalent of always adding "^" to the front of your regex.
