unzipping a zip file with non-utf8 encoding by Python3

unzip.py

import zipfile
import sys
from pathlib import Path


def unzip(f, encoding, v):
    with zipfile.ZipFile(f) as z:
        for i in z.namelist():
            n = Path(i.encode('cp437').decode(encoding))
            if v:
                print(n)
            if i[-1] == '/':
                if not n.exists():
                    n.mkdir()
            else:
                with n.open('wb') as w:
                    w.write(z.read(i))

if __name__ == '__main__':
    for i in sys.argv[1:]:
        unzip(i, 'cp932', 1)

Thanks. This saves a lot of time.

Thanks

Thanks

it works well.

but why cp437?

and why not ZipInfo.is_dir to test if it is directory?

cp437: see https://github.com/python/cpython/blob/0d70227e419ab78c44d81b4ea6ae8aaf769470e6/Lib/zipfile.py#L1332-L1336
is_dir: I don't remember. but ZipInfo.is_dir does the same https://github.com/python/cpython/blob/0d70227e419ab78c44d81b4ea6ae8aaf769470e6/Lib/zipfile.py#L534-L536

cool!

Not robust enough, but still worked like a charm. Inspired me to enhance a new version of this.

Incredible! I struggled an hour for this.
