VertexFrame schema

---

schema

Current frame column names and types.

Parameters: Returns:

: list

list of tuples of the form (<column name>, <data type>)

The schema of the current frame is a list of column names and associated data types. It is retrieved as a list of tuples. Each tuple has the name and data type of one of the frame’s columns.

Examples

>>> frame.schema
[(u'name', <type 'unicode'>), (u'age', <type 'numpy.int32'>), (u'tenure', <type 'numpy.int32'>), (u'phone', <type 'unicode'>)]

Note how the types shown are the raw, underlying types used in python. To see the schema in a friendlier format, used the __repr__ presentation, invoke by simply entering the frame:

>>> frame
Frame "example_frame"
row_count = 4
schema = [name:unicode, age:int32, tenure:int32, phone:unicode]
status = ACTIVE  (last_read_date = -etc-)
