Could zipfile module process the zip data in memory?

[人言落日是天涯，望极天涯不见家]

I made a C/S network program, the client receive the zip file from the
server, and read the data into a variable. how could I process the
zipfile directly without saving it into file.
In the document of the zipfile module, I note that it mentions the
file-like object? what does it mean?

class ZipFile( file[, mode[, compression[, allowZip64]]])
         Open a ZIP file, where file can be either a path to a file (a
string) or a file-like object.

Thanks!
