Dear Guys, I have to run the next regexp change in a stream:
import re wrongcode = re.compile(r'(.*)b24704T') f = open('testfile.txt') while 1: sequence = f.read(1024) sequence = wrongcode.sub(r'\1b24700T', sequence) print sequence My original solution was to keep the last part of the sequence till the next sequence hasn't been arrived while 1: try: sequence = f.read(1024) try: sequence = prevend + sequence except: pass sequence = wrongcode.sub(r'\1b24700T', sequence) prevend = sequence[-20:] # keep the end of the sequence till we haven't got the complete picture sequence = sequence[:-20] # the first part was checked correctly if not sequence: print prevend break print sequence except: break In the real sample it works on an IP socket. Have got someone better idea ? Probably it is better to work with two sequence.
