Just after posting I realised it would be better to do:
found2 = False
for line in file("prueba.txt"):
found2 = found2 or line.startswith('2')
if found2: print line
The continue was superfluous and the if test
less efficient that the boolean test.
line.startswith seems a more appropriate test too,
and should be more efficient on long lines.
