pandas.DataFrame.itertuples

DataFrame.itertuples(index=True, name='Pandas')[source]

Iterate over DataFrame rows as namedtuples.

Parameters:
index : bool, default True

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

name : str, default “Pandas”

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

Yields:
collections.namedtuple

Yields a namedtuple for each row in the DataFrame with the first field possibly being the index and following fields being the column values.

DataFrame.iterrows
Iterate over DataFrame rows as (index, Series) pairs.
DataFrame.iteritems
Iterate over (column name, Series) pairs.

Notes

The column names will be renamed to positional names if they are invalid Python identifiers, repeated, or start with an underscore. With a large number of columns (>255), regular tuples are returned.

Examples

>>> df = pd.DataFrame({'num_legs': [4, 2], 'num_wings': [0, 2]},
...                   index=['dog', 'hawk'])
>>> df
      num_legs  num_wings
dog          4          0
hawk         2          2
>>> for row in df.itertuples():
...     print(row)
...
Pandas(Index='dog', num_legs=4, num_wings=0)
Pandas(Index='hawk', num_legs=2, num_wings=2)

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)
...
Pandas(num_legs=4, num_wings=0)
Pandas(num_legs=2, num_wings=2)

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

>>> for row in df.itertuples(name='Animal'):
...     print(row)
...
Animal(Index='dog', num_legs=4, num_wings=0)
Animal(Index='hawk', num_legs=2, num_wings=2)
