# Bug report
### Bug description:
Adding a directory entry to a zip file on the basis of a `ZipInfo` object (to pick up metadata) fails because `ZipFile` evidently expects the object to have a `CRC` attribute even though it's a directory rather than a file. I can work around this bug by storing the `ZipInfo` in a variable and giving it a nominal CRC (namely 0), but that shouldn't be necessary. Specifically,
```python
import os
import zipfile
with zipfile.ZipFile("bug.zip", mode = "w") as z:
os.chdir('/')
z.mkdir(zipfile.ZipInfo.from_file('usr'))
```
fails:
```
File ".../zipfile-bug.py", line 6, in <module>
z.mkdir(zipfile.ZipInfo.from_file('usr'))
File "/usr/lib/python3.12/zipfile/__init__.py", line 1935, in mkdir
self.fp.write(zinfo.FileHeader(False))
^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.12/zipfile/__init__.py", line 460, in FileHeader
CRC = self.CRC
^^^^^^^^
AttributeError: 'ZipInfo' object has no attribute 'CRC'
```
Could you please take a look?
Thanks!
