Python Package: `No module named 'duckdb.duckdb'` Build Error
**Problem:**
Building the Python package succeeds but the package cannot be imported:  
```batch
cd tools/pythonpkg/
python3 -m pip install .
python3 -c "import duckdb"
```  
This returns the following error message:  
```console
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/duckdb/tools/pythonpkg/duckdb/__init__.py", line 4, in <module>
import duckdb.functional as functional
File "/duckdb/tools/pythonpkg/duckdb/functional/__init__.py", line 1, in <module>
from duckdb.duckdb.functional import (
ModuleNotFoundError: No module named 'duckdb.duckdb'
```  
**Solution:**
The problem is caused by Python trying to import from the current working directory.
To work around this, navigate to a different directory (e.g., `cd ..`) and try running Python import again.
