Import from Numpy
It is possible to query Numpy arrays from DuckDB.
There is no need to register the arrays manually –
DuckDB can find them in the Python process by name thanks to [replacement scans](#docs:guides:glossary::replacement-scan).
For example:  
```python
import duckdb
import numpy as np

my_arr = np.array([(1, 9.0), (2, 8.0), (3, 7.0)])

duckdb.sql("SELECT * FROM my_arr")
```  
```text
┌─────────┬─────────┬─────────┐

│ double  │ double  │ double  │
├─────────┼─────────┼─────────┤
│     1.0 │     2.0 │     3.0 │
│     9.0 │     8.0 │     7.0 │
└─────────┴─────────┴─────────┘
