Python 解压文件、压缩文件（zip,rar）_python代码zip自动解压

1. python 解压zip压缩包或rar压缩包

import zipfile
# from unrar import rarfile   # python2
import rarfile  # python3
 
 
def zip_decompress(file_path, new_path):
    """支持中文的解压缩程序
       file_path：原压缩包文件路径
       new_path：新文件夹路径
    """
    if file_path.split('.')[-1] == 'zip':
        z = zipfile.ZipFile(file_path, 'r')
        z.extractall(path=new_path)
    else:
        z = rarfile.RarFile(file_path, 'r')
        z.extractall(path=new_path)
 
 
if __name__ == "__main__":
    file_path = r"C:\test\zip_test\Django.rar"
    new_path = r"C:\test\zip_test"
    zip_decompress(file_path, new_path)
 

2. python将文件/文件夹压缩为zip压缩包

import os
import zipfile
 
 
def zipDir(dirpath, target_path):
    """
    压缩指定文件夹
    :param dirpath: 目标文件夹路径
    :param target_path: 压缩文件保存路径
    """
    pre_len = len(os.path.dirname(target_path))
    zip = zipfile.ZipFile(target_path, "w", zipfile.ZIP_DEFLATED)
    for path, dirnames, filenames in os.walk(dirpath):
        # # 1.去掉目标跟路径，只对目标文件夹下边的文件及文件夹进行压缩
        # fpath = path.replace(dirpath, '')
        # for filename in filenames:
        #     pathfile = os.path.join(path, filename)
        #     arcname = os.path.join(fpath, filename)  # 归档文件
        #     zip.write(pathfile, arcname)
 
        # 2. 带文件夹压缩
        for filename in filenames:
            pathfile = os.path.join(path, filename)
            arcname = pathfile[pre_len:].strip(os.path.sep)  # 相对路径
            zip.write(pathfile, arcname)
    zip.close()
 
 
if __name__ == "__main__":
    dirpath = r"C:\test\zip_test\pdfconver"
    target_path = r"C:\test\zip_test\pdfconver.zip"
    zipDir(dirpath, target_path)
