Nope.
I think Python is a programmer's language, not a whack-something-together
script language for text processing (although it is used that way).
Any decent programmer has no need of this construct, since the time to
lookup how

Yes, indeed. I think it's a very common coding problem
(with plenty of mostly analogous variations) that has
these very common pitfalls:
1) People often forget t

Below is the easy solution. To get even better performance, or if '<' is not
always at the start of the line, you would have to implement the
something like
name=None
lines=[]
for line in open('yourfilename.txt'):
if line.startwith('>'):
if name!=None:
print 'Here is the record', name
print lines
print
name=line.stripr('\r')
lines=[]
else:
lines.append(line.str
I wanted to also say that this file is really huge, so I cannot
just do a read() and then split on ">" to get a record
