Thanks! Seems you can also use gzip.decompress() with a bytes object directly: https://docs.python.org/3/library/gzip.html#gzip.decompress.

You're welcome! 😄

@paulistoan, great point, I've updated it now.

gzip.compress() exists too since 3.2. This whole gist is now unnecessary, except for 3.0 and 3.1. (Except that gzip.decompress() doesn't exist in 3.0 and 3.1 either so the first commit of this gist is needed there.)

Great point @jack980517, I've updated it to reflect that.
