zipfile — Work with ZIP archives — Python 3.10.2 documentationhttps://docs.python.org/3/library/zipfile.html

This module provides a portable way of using operating system dependent functionality.

With this way,you can read or write a file and something about file.

import zipfile #引入文件处理函数，便于文件解压缩
import os   #python提供的处理文件和目录的方法

#解压src_path路径下的数据到target_path路径下
def unzip_data(src_path,target_path):
    # 判断，如果target_path文件为空则执行如下操作
    if(not os.path.isdir(target_path)):
        读取该文件
        z = zipfile.ZipFile(src_path, 'r')   
        #将上一行代码中打开的源文件解压到目标文件目录
        z.extractall(path=target_path)
        z.close()



#调用函数
unzip_data()

zipfile.ZipFile()
# Open the ZIP file with mode read 'r', write 'w', exclusive create 'x', or append 'a'

ZipFile.extractall(path=None, members=None, pwd=None)

Extract all members from the archive to the current working directory.

注意：代码的可复用与模块化

os.listdir()

Return a list containing the names of the files in the directory.

os.path.splitext(path)

Split the pathname path into a pair (root, ext) such that root + ext == path
