eland.DataFrame.itertuples

DataFrame.itertuples(index: bool = True, name: Optional[str] = 'Eland') → Iterable[Tuple[Any, ...]]

Iterate over eland.DataFrame rows as namedtuples.

Parameters
index: bool, default True

If True, return the index as the first element of the tuple.

name: str or None, default “Eland”

The name of the returned namedtuples or None to return regular tuples.

Returns
iterator

An object to iterate over namedtuples for each row in the DataFrame with the first field possibly being the index and following fields being the column values.

Iterate over eland.DataFrame rows as (index, pandas.Series) pairs.

Examples

>>> df = ed.DataFrame('localhost:9200', 'flights', columns=['AvgTicketPrice', 'Cancelled']).head()
>>> df
   AvgTicketPrice  Cancelled
0      841.265642      False
1      882.982662      False
2      190.636904      False
3      181.694216       True
4      730.041778      False
<BLANKLINE>
[5 rows x 2 columns]
>>> for row in df.itertuples():
...     print(row)
Eland(Index='0', AvgTicketPrice=841.2656419677076, Cancelled=False)
Eland(Index='1', AvgTicketPrice=882.9826615595518, Cancelled=False)
Eland(Index='2', AvgTicketPrice=190.6369038508356, Cancelled=False)
Eland(Index='3', AvgTicketPrice=181.69421554118, Cancelled=True)
Eland(Index='4', AvgTicketPrice=730.041778346198, Cancelled=False)

By setting the index parameter to False we can remove the index as the first element of the tuple:

>>> for row in df.itertuples(index=False):
...     print(row)
Eland(AvgTicketPrice=841.2656419677076, Cancelled=False)
Eland(AvgTicketPrice=882.9826615595518, Cancelled=False)
Eland(AvgTicketPrice=190.6369038508356, Cancelled=False)
Eland(AvgTicketPrice=181.69421554118, Cancelled=True)
Eland(AvgTicketPrice=730.041778346198, Cancelled=False)

With the name parameter set we set a custom name for the yielded namedtuples:

>>> for row in df.itertuples(name='Flight'):
...     print(row)
Flight(Index='0', AvgTicketPrice=841.2656419677076, Cancelled=False)
Flight(Index='1', AvgTicketPrice=882.9826615595518, Cancelled=False)
Flight(Index='2', AvgTicketPrice=190.6369038508356, Cancelled=False)
Flight(Index='3', AvgTicketPrice=181.69421554118, Cancelled=True)
Flight(Index='4', AvgTicketPrice=730.041778346198, Cancelled=False)
