write an iterator that filters line to your liking and use it as input
to cvs.reader:
def CommentStripper (iterator):
for line in iterator:
if line [:1] == '#':
continue
if not line.strip ():
continue
yield line
reader = csv.reader (CommentStripper (open (csv_file)))
CommentStripper is actually quite useful for other files. Of course
there might be differences if a comment starts
- on the first character
- on the first non-blank character
- anywhere in the line
