import gzip,re

file = "/arcs/some.arc.gz"

ARC_PATTERN = re.compile("(^.*:[^ ]*)\\s([0-9.]+)\\s(\\d+)\\s(\\S+)\\s(\\d+)$")

def readchunk(fp):
    meta = ARC_PATTERN.match(fp.readline()).groups()
    page = fp.read(long(meta[4])+1)
    return (meta,page)

def main():
    f = gzip.open(file,'rb')
    print readchunk(f)
    print readchunk(f)

if __name__ == '__main__':
    main()

windows下注意加rb，不然会坑。
