Do you need the remainder within the parser functions? If not you could
split the data into chunks of 100 bytes and pass an iterator from function
to function. Untested:
def iter_chunks(data, chunksize):
offset = chunksize
while True:
result = data[offset:offset + chunksize]
if not result:
break
yield result
def parser1(data):
chunk = data.next()
# ...
parser2(data)
def parser2(data):
chunk = data.next()
# ...
parser3(data)
# ...
def main():
# Read or create data.
# ...
parser1(iter_chunks(data, 100))
