You might like to try the zipstream version of zipfile. For example, to compress stdin to stdout as a zip file holding the data as a file named TheLogFile using iterators:

#!/usr/bin/python3
import sys, zipstream
with zipstream.ZipFile(mode='w', compression=zipstream.ZIP_DEFLATED) as z:
    z.write_iter('TheLogFile', sys.stdin.buffer)
    for chunk in z:
        sys.stdout.buffer.write(chunk)
