# Example 1: Create two feature groups and then create a new feature
# group by combining those two feature groups.
# Creating first feature group.
>>> f1 = Feature("sales_Jan", column=df.Jan)
>>> f2 = Feature("sales_Feb", column=df.Feb)
>>> entity = Entity(name="sales", columns='accounts')
>>> data_source = DataSource("sales", source=df.show_query())
>>> fg1 = FeatureGroup(name="sales_jan_feb", entity=entity, features=[f1, f2], data_source=data_source)
>>> fg1

# Creating second feature group.
>>> f3 = Feature("sales_Mar", column=df.Mar)
>>> f4 = Feature("sales_Apr", column=df.Apr)
>>> data_source = DataSource("sales_Mar_Apr", source=df.show_query())
>>> fg2 = FeatureGroup(name="sales_Mar_Apr", entity=entity, features=[f3, f4], data_source=data_source)
