小知识：python解压zip文件

import zipfile
import os

def un_zip(file_name):
    """unzip zip file"""
    zip_file = zipfile.ZipFile(file_name)
    if os.path.isdir(file_name + "_files"):
        pass
    else:
        os.mkdir(file_name + "_files")
    for names in zip_file.namelist():
        zip_file.extract(names,file_name + "_files/")
    zip_file.close()

un_zip("E:\\fiddler_data\\Fiddler_20171215_23-52-45.saz")
