Feature or enhancement

Proposal:

Scenario

You have a larger system generating zip files, often they each contain many of the same files, and you've got a big parallel build setup. All of these would benefit from pre-computing, distributing, and caching the compression of individual members going into the zip file.

Proposal

On zipfile.ZipFile write writestr and open(..., mode="w") methods, add arguments allowing the already compressed data to be provided as-is so that the zipfile modules internal compression step is skipped on those.

Has this already been discussed elsewhere?
