I should not post this, especially on a tutor list, but as you already have
a fairly robust solution here's an evil hack:
$ cat make_partial_archive.py
#!/usr/bin/env python3
import os
import shutil
from unittest.mock import patch
_os_path_isfile = os.path.isfile
def accept(path):
if path in ["delta/one.txt", "beta.txt"]:
print("skipping %r" % path)
return False
return _os_path_isfile(path)
if __name__ == "__main__":
with patch("os.path.isfile", side_effect=accept):
shutil.make_archive("archive", "zip", "data")
$ tree data
data
├── alpha.txt
├── beta.txt
├── delta
│ ├── one.txt
│ ├── three.txt
│ └── two.txt
└── gamma.txt
1 directory, 6 files
$ python3 make_partial_archive.py
skipping 'beta.txt'
skipping 'delta/one.txt'
$ unzip archive.zip -d tmp
Archive: archive.zip
inflating: tmp/gamma.txt
inflating: tmp/alpha.txt
inflating: tmp/delta/two.txt
inflating: tmp/delta/three.txt
$
Explanation: The script manipulates the make_archive() implementation for
zip files by temporarily replacing os.path.isfile() with a custom accept()
function.
