It is always good to see that the batteries included in Rocket Python actually work…
Here is an example on how to compress a MVS file into a zip file:
from zipfile import ZipFile
zf = 'mm.zip'
fn = '//MM.PRINTS'
fz = fn.lstrip('/') # remove '/' from the MVS file name
with open(fn, 'r') as fd:
qstr = fd.read()
with ZipFile(zf, 'w') as zd:
# zd.write(fn,fz) <- does not work because internally called
# os.stat() does not find z/OS dataset
This runs in Python 2.7.13, File must fit into 64 bit memory.
