这是处理基本功能的Python类。我已将其用于自己的工作：
import py7zlibclass SevenZFile(object): @classmethod def is_7zfile(cls, filepath): ''' Class method: determine if file path points to a valid 7z archive. ''' is7z = False fp = None try: fp = open(filepath, 'rb') archive = py7zlib.Archive7z(fp) n = len(archive.getnames()) is7z = True finally: if fp: fp.close() return is7z def __init__(self, filepath): fp = open(filepath, 'rb') self.archive = py7zlib.Archive7z(fp) def extractall(self, path): for name in self.archive.getnames(): outfilename = os.path.join(path, name) outdir = os.path.dirname(outfilename) if not os.path.exists(outdir): os.makedirs(outdir) outfile = open(outfilename, 'wb') outfile.write(self.archive.getmember(name).read()) outfile.close()
