Err, no, that does not apply to "random."  If the data is truly random
then it does not matter whether you have 5 bytes or 5 GB.  There is no
pattern to discern, and having more chunks of random data won't make it
possible to compress.

People are taking issue with your claim that you can compress random
data.  Clearly you cannot, by your own admission about requiring more
chunks of data (see above), and also by the irrefutable logical
principles Steven D'Aprano layed out.

Probably time to mute this thread. It's not related to Python.
