Hi all,
I have a feeling that I should solve this by a context manager but
since I've never used them I'm not sure what the optimal (in the
python sense) solution is. So basically what I do all the time is
this:
for line in open( 'myfile' ):
if not line:
# discard empty lines
continue
if line.startswith( '#' ):
# discard lines starting with #
continue
items = line.split( )
if not items:
# discard lines with only spaces, tabs, etc
continue
process( items )
You see I'd like to ignore lines which are empty, start with a #, or
are only white space. How would I write a context manager so that the
above simply becomes
with some_tricky_stuff( 'myfile' ) as items:
process( items )
Cheers,
Daniel
