如下所示：
import os
import re
import 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)
