packing things back to regular expression

[Amit Gupta]

Before I read the message: I screwed up.

Let me write again

>> x = re.compile("CL(?P<name1>[a-z]+)")
# group name "name1" is attached to the match of lowercase string of
alphabet
# Now I have a dictionary saying {"name1", "iamgood"}
# I would like a function, that takes x and my dictionary and return
"CLiamgood"
# If my dictionary instead have {"name1", "123"}, it gives error on
processingit
#
# In general, I have reg-expression where every non-trivial match has
a group-name. I want to do the reverse of reg-exp match. The function
can take reg-exp and replace the group-matches from dictionary
# I hope, this make it clear.
