You mean you have a text file and you want to find all the lines between
a line starting with  "start" and one starting with "end".

REs are not your best method here, just do something like this:

lines = open('myfile', 'r').readlines()
printing = 0
for line in lines:
    if line[:5]=='start': printing=1
    if line[:3]=='end':  printing=0
    if printing: print line

Or something like that.  I'm sure there are cleverer ways, but
that should do what you ask for.
