gzip original file size.

[sebsauvage]

Hello !

I'm using the gzip module of Python.
I'm trying to know the original size of a file compressed in .gz.

How could I do this ?

Do I have to perform GzipFile()/seek(0,2)/tell() to know the original file size ? <yuk!>
Do I have to parse myself the gzip header ? <grin>
Or is there a smarter way of doing this ?

Thanks in advance.
