[Tutor] String Processing Query

[spawgi at gmail.com]

This snipped also works - may be there is a better solution -

', '*']
>>> s = ''
>>> for line in lines:
line = line.rstrip('\n')
 if line.startswith('>from header'):
continue
elif line.startswith('*'):
 s = s + '\n'
else:
s = s + line

>>> s
'abcdefghijklmnopqrstuvwxyz\npoiuytrewqlkjhgfdsamnbvcxz\n'
>>> print s
abcdefghijklmnopqrstuvwxyz
poiuytrewqlkjhgfdsamnbvcxz


Thanks and Regards,
Sumod
