input record seperator (equivalent of "$|" of perl)

[M.E.Farmer]

What about a generator and xreadlines for those really large files:

py>def recordbreaker(recordpath, seperator='#'):
...   rec = open(recordpath ,'r')
...   xrecord = rec.xreadlines()
...   a =[]
...   for line in xrecord:
...       sep = line.find(seperator)
...       if  sep != -1:
...           a.append(line[:sep])
...           out = ''.join(a)
...           a =[]
...           a.append(line[sep+1:])
...           yield out
...       else:
...           a.append(line)
...   if a:
...       yield ''.join(a)
...   rec.close()
...
py>records = recordbreaker('/tmp/myrecords.txt')
py>for item in records:
...    print item
