使用python 打开文件并做匹配处理

import osimport reimport string file = open("data2.txt")p1 = re.compile(r"^(\d{16})\s+(\d{3})")re.compile(p1)for line in file:        print(line)        match1 = re.search(p1,line)        #print(match1.group(0))

        sCard = match1.group(1)        sValue=match1.group(2)        print(sCard)        print(sValue)        b = re.findall(r"\d{2}",sCard)        # remove r or one \ if want signle \        c =r'\\x'.join(b)        c= r'\\x'+c        print(c)
