正则split的使用

import re
#\s 空格  +号表示至少出现一次
# path = 'C:\\Users\\cz\Desktop\py06\\PY6_Day01\\爬虫作业\\2018_03_07\\05_split.py'

#前面加r表示元字符
path = r'C:\Users\cz\Desktop\py06\PY6_Day01\爬虫作业\2018_03_07\05_split.py'

#用\做分割
pattern = re.compile(r'\\')
s = pattern.split(path)
print(s)
filename = s[-1]
print(filename)
