Title
Body
I got a file which includes many lines of plain utf-8 text. Such as below, by the by, it's Chinese. PROCESS：类型：关爱积分[NOTIFY] 交易号：2012022900000109 订单号：W12022910079166 交易金额：0.01元 交易状态：true 2012-2-29 10:13:08 The file itself was saved in utf-8 format. file name is xx.txt here is my python code, env is python2.7 #coding: utf-8 import re pattern = re.compile(r'交易金额：(\d+)元') for line in open('xx.txt'): match = pattern.match(line.decode('utf-8')) if match: print match.group() The problematic thing here is I got no results. I wanna get the decimal string from 交易金额：0.01元 , in here, which is 0.01 . Why doesn't this code work? Can anyone explain it to me, I got no clue whatsoever.
