 - **These capabilities are very new.** As data warehouses develop new features, we expect them to offer cheaper, faster, and more intuitive mechanisms for deploying Python transformations. **We reserve the right to change the underlying implementation for executing Python models in future releases.** Our commitment to you is around the code in your model `.py` files, following the documented capabilities and guidance we're providing here.
 - **Lack of `print()` support.** The data platform runs and compiles your Python model without dbt's oversight. This means it doesn't display the output of commands such as Python's built-in [`print()`](https://docs.python.org/3/library/functions.html#print) function in dbt's logs.

+    The following explains other methods you can use for debugging, such as writing messages to a dataframe column:
+
+    - Using platform logs: Use your data platform's logs to debug your Python models.
+    - Return logs as a dataframe: Create a dataframe containing your logs and build it into the warehouse.
+    - Develop locally with DuckDB: Test and debug your models locally using DuckDB before deploying them.
+
+    Here's an example of debugging in a Python model:
+
+    ```python
+    def model(dbt, session):
+        dbt.config(
+            materialized = "table"
+        )
+
+        df = dbt.ref("my_source_table").df()
+
+        # One option for debugging: write messages to temporary table column
+        # Pros: visibility
+        # Cons: won't work if table isn't building for some reason
+        msg = "something"
+        df["debugging"] = f"My debug message here: {msg}"
+
+        return df

 As a general rule, if there's a transformation you could write equally well in SQL or Python, we believe that well-written SQL is preferable: it's more accessible to a greater number of colleagues, and it's easier to write code that's performant at scale. If there's a transformation you _can't_ write in SQL, or where ten lines of elegant and well-annotated Python could save you 1000 lines of hard-to-read Jinja-SQL, Python is the way to go.
