You can now use Automatic Liquid Clustering with Python:

# Enabling Automatic Liquid Clustering on a new table
@dlt.table(cluster_by_auto=True)
def tbl_with_auto():
   return spark.range(5)

# Manually choosing a clustering key initially, followed by automatic clustering
@dlt.table(cluster_by_auto=True, cluster_by=["id"])
def tbl_with_auto_and_initial_hint():
   return spark.range(5)
