If you need a Parquet file that contains a UUID column (for testing
purposes), DuckDB can write one like this:
```py
import duckdb
con = duckdb.connect()
con.execute("CREATE TABLE t1 AS SELECT gen_random_uuid() a FROM range(0,
16);")
con.execute("copy t1 to 'uuid_test.parquet'")
```
Thanks @pdet for this example code.
