Mam problem z pobraniem Pythona do odczytu konkretnych linii. Nad czym pracuję to coś takiego:

lines of data not needed
lines of data not needed
lines of data not needed

--------------------------------------
    ***** REPORT 1 *****
--------------------------------------

[key] lines of interest are here
[key] lines of interest are here
[key] lines of interest are here
[key] lines of interest are here
[key] lines of interest are here      #This can also be the EOF

--------------------------------------    
    ***** REPORT 2 *****
--------------------------------------

lines of data not needed
lines of data not needed
lines of data not needed         #Or this will be the EOF

Próbowałem czegoś takiego jak:

flist = open("filename.txt").readlines()

for line in flist:
  if line.startswith("\t**** Report 1"):
    break
for line in flist:
  if line.startswith("\t**** Report 2"):
    break
  if line.startswith("[key]"):
    #do stuff with data

Mam jednak problem, gdy plik kończy się bez separatora końcowego ... Tak jak wtedy, gdy raport # 2 nie jest wyświetlany. Jakie jest lepsze podejście?
