Overview: Bus: Exporter

Bus.to_series()[source]

Return a Series with the Frame contained in this Bus. If the Bus is associated with a Store, all Frame will be loaded into memory and the returned Bus will no longer be associated with the Store.

>>> b = sf.Bus.from_frames((sf.Frame(np.arange(6).reshape(3,2), index=('p', 'q', 'r'), columns=('a', 'b'), name='x'), sf.Frame((np.arange(6).reshape(3,2) % 2).astype(bool), index=('p', 'q', 'r'), columns=('c', 'd'), name='y')), name='i')

Bus.to_sqlite(fp, *, config=None)

Write the complete Bus as an SQLite database file.

Parameters:
