Python解压 rar、zip、tar文件的方法

import rarfile
import os
rar=rarfile.RarFile(filename, mode='r') # mode的值只能为'r'
# 判断同名文件夹是否存在，若不存在则创建同名文件夹
if os.path.isdir(os.path.splitext(filename)[0]):
 rf_list = rf.namelist() # 得到压缩包里所有的文件 
 print('rar文件内容', rf_list) 
else:
 os.mkdir(os.path.splitext(filename)[0])
rar.extractall(os.path.splitext(filename)[0]) # 解压文件
rar.close() # 关闭文件，必须有，释放内存

import zipfile
import os
zip_file = zipfile.ZipFile(filename)
if os.path.isdir(os.path.splitext(filename)[0]):
 zip_list = zip_file.namelist() # 得到压缩包里所有文件 
 print('zip文件内容', zip_list) 
else:
 os.mkdir(os.path.splitext(filename)[0])
for f in zip_list:
 zip_file.extract(f, os.path.splitext(filename)[0]) # 循环解压文件到指定目录
zip_file.close()

import tarfile
import os

tar = tarfile.open(filename, mode = "r:gz") #"r:gz"表示 open for reading with gzip compression
tar.extractall(path=os.path.splitext(filename)[0]) # 将tar.gz文件解压到temp文件夹下
tar.close()

import os
import zipfile
def unzip_resource(zip_path):
  file_name = os.path.basename(zip_path)
  file_dir = os.path.dirname(zip_path)
  if os.path.splitext(zip_path)[1] == '.zip':
    file_zip = zipfile.ZipFile(zip_path, 'r')
    for resource_file in file_zip.namelist():
      file_zip.extract(resource_file, file_dir + '/' + file_name.replace('.zip', ''))
  file_path = zip_path.replace('.zip', '')
  resource_path = file_path + '/'
  return resource_path

import os
import zipfile
def abcZip(dir_path, file_name):
  with zipfile.ZipFile(file_name, 'w', zipfile.ZIP_DEFLATED) as target:
    for dirpath, dirnames, filenames in os.walk(dir_path):
      fpath = dirpath.replace(dir_path, '')
      fpath = fpath and fpath + os.sep or ''
      for filename in filenames:
        # file_list.append(os.path.join(dirpath,filename))
        # print(os.path.join(dirpath,filename)
        if (filename.__contains__('.DS_Store')):
          continue
        target.write(os.path.join(dirpath, filename), fpath + filename)
  target.close()
