python 解压密码zip

import zipfile
import itertools
 
filename = "297.zip"
# 创建一个解压的函数，入参为文件名和密码
# 并使用try-except，避免报错中断程序。
def uncompress(file_name, pass_word):
    try:
        with zipfile.ZipFile(file_name) as z_file:
            z_file.extractall("./", pwd=pass_word.encode("utf-8"))
        return True
    except:
        return False
 
# chars是密码可能的字符集
chars = "abcdefghijklmnopqrstuvwxyz0123456789"

        if not result:
