我正在尝试编写一个python程序,最终将获取文件的命令行参数,确定它是否是tar或zip等文件,然后相应地对其进行exctract.我只是试图让tar部分工作,我得到了多个错误.我正在检查的文件位于我的〜/目录中.任何想法都会很棒.

#!/usr/bin/python

import tarfile
import os

def open_tar(file):
    if tarfile.is_tarfile(file):
        try:
            tar = tarfile.open("file")
            tar.extractall()
            tar.close()
        except ReadError:
            print "File is somehow invalid or can not be handled by tarfile"
        except CompressionError:
            print "Compression method is not supported or data cannot be decoded"
        except StreamError:
            print "Is raised for the limitations that are typical for stream-like TarFile objects."
        except ExtractError:
            print "Is raised for non-fatal errors when using TarFile.extract(), but only if TarFile.errorlevel== 2."

if __name__ == '__main__':
    file = …
