使用python 打开文件并做匹配处理的实例

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)
