Python压缩文件夹 tar.gz .zip

打包压缩生成 XXX.tar.gz 文件

 import os
 import tarfile
 
 if os.path.exists(outputFileName):
     with tarfile.open(outputFileName + ".tar.gz", "w:gz") as tar:
         tar.add(sourceDir, arcname=os.path.basename(sourceDir))

open的原型是：

 tarfile.open(name=None, mode='r', fileobj=None, bufsize=10240, **kwargs)

tarfile.open的mode有很多种：

'r' or 'r:*'	Open for reading with transparent compression (recommended).
'r:'	Open for reading exclusively without compression.
'r:gz'	Open for reading with gzip compression.
'r:bz2'	Open for reading with bzip2 compression.
'a' or 'a:'	Open for appending with no compression. The file is created if it does not exist.
'w' or 'w:'	Open for uncompressed writing.
'w:gz'	Open for gzip compressed writing.
'w:bz2'	Open for bzip2 compressed writing.

在写打包代码的过程中，使用tar.add()增加文件时，会把文件本身的路径也加进去，加上arcname就能根据自己的命名规则将文件加入tar包

打包压缩生成 XXX.zip 文件

 import os
 import zipfile
 
 zip_file = zipfile.ZipFile(report_path + ".zip", "w", zipfile.ZIP_DEFLATED)
 for dirpath, dirnames, filenames in os.walk(report_path):  # report_path是要压缩的文件夹
     fpath = dirpath.replace(report_path, '')
     fpath = fpath and fpath + os.sep or ""
     for filename in filenames:
         zip_file.write(os.path.join(dirpath, filename), fpath + filename)  # 只能一个文件一个文件地往里写
 zip_file.close()
