Méthode pandas.Series.memory_usage

Signature de la méthode memory_usage

def memory_usage(self, index: 'bool' = True, deep: 'bool' = False) -> 'int' 

Description

help(Series.memory_usage)

Return the memory usage of the Series.

The memory usage can optionally include the contribution of
the index and of elements of `object` dtype.

Parameters
----------
index : bool, default True
    Specifies whether to include the memory usage of the Series index.
deep : bool, default False
    If True, introspect the data deeply by interrogating
    `object` dtypes for system-level memory consumption, and include
    it in the returned value.

Returns
-------
int
    Bytes of memory consumed.

See Also
--------
numpy.ndarray.nbytes : Total bytes consumed by the elements of the
    array.
DataFrame.memory_usage : Bytes consumed by a DataFrame.

Examples
--------
>>> s = pd.Series(range(3))
>>> s.memory_usage()
152

Not including the index gives the size of the rest of the data, which
is necessarily smaller:

>>> s.memory_usage(index=False)
24

The memory footprint of `object` values is ignored by default:

>>> s = pd.Series(["a", "b"])
>>> s.values
array(['a', 'b'], dtype=object)
>>> s.memory_usage()
144
>>> s.memory_usage(deep=True)
244
