Python在模块中没有等效的Unix uncompress，这是您需要解压缩的。 Z文件。您可能需要a）外壳到Unix compress命令，b）外壳到gzip，c）外壳到7-zip（gzip和7-zip都具有解压缩.Z文件的能力），d）修改在C中原始的解压缩代码并链接到Python（该代码可在线获得），或者e）在本机Python中编写自己的LZW解压缩器。

Python does not have the equivalent of Unix uncompress available in a module, which is what you'd need to decompress a .Z file. You would either need to a) shell out to the Unix compress command, b) shell out to gzip, c) shell out to 7-zip (both gzip and 7-zip have the ability to decompress .Z files), d) modify the original uncompress code in C and link that to Python (the code is available online), or e) write your own LZW decompressor in native Python.

对于d），您可以在mathematica.stackexchange.com 上的答案中找到我编写的一些C代码来。请参见 unlzw（）函数。

For d), you can find some C code I wrote to do this job in this answer on mathematica.stackexchange.com. See the unlzw() function.
