Snowflake supports executing Python code using its built-in task functionality. Tasks allow scheduling and executing SQL queries, Stored Procedures and Python scripts at a particular time or periodic intervals.

To execute Python code in Snowflake, follow these steps:

1. In Snowflake, create a new task using the CREATE TASK command.
2. Set the task to execute the Python code by providing the code within a SnowSQL statement of the task.
3. Schedule the task to run at a particular time or period using the CRON expression.

For example, the following code creates a new task that runs a Python script every hour:

CREATE OR REPLACE TASK my_python_task
  WAREHOUSE = my_warehouse
  SCHEDULE = '1 HOUR'
  AS
  CALL my_python_script();

The my_python_script function in the above code should be created beforehand and should contain the necessary Python code.

Note that for this to work, you need to have the necessary Python libraries installed in your Snowflake instance. You can install them using the Snowflake's CREATE EXTERNAL FUNCTION command, which allows installing Python libraries from external sources like PyPI repositories.
