Ways to fix

Summary: make sure you use a slash at the end of the path your want to iter over:

Code to reproduce (WRONG):

import zipp, io

data = io.BytesIO()
zf = zipp.zipfile.ZipFile(data, 'w')
zf.writestr('fol/file.txt', 'content of a')

p = zipp.Path(zf, 'fol')

print('List of files', list(p.iterdir()))

Working version (Fixed):

import zipp, io

data = io.BytesIO()
zf = zipp.zipfile.ZipFile(data, 'w')
zf.writestr('fol/file.txt', 'content of a')

p = zipp.Path(zf, 'fol/') # <--- HERE IS A FIX WE ADDED SLASH

print('List of files', list(p.iterdir()))
