#  pandas.Index.size  #

_ property  _ Index.  size  [ [source]  ](https://github.com/pandas-
dev/pandas/blob/v2.2.2/pandas/core/base.py#L448-L474) #

    

Return the number of elements in the underlying data.

Examples

For Series:

    
    
    >>> s = pd.Series(['Ant', 'Bear', 'Cow'])
    >>> s
    0     Ant
    1    Bear
    2     Cow
    dtype: object
    >>> s.size
    3
    

For Index:

    
    
    >>> idx = pd.Index([1, 2, 3])
    >>> idx
    Index([1, 2, 3], dtype='int64')
    >>> idx.size
    3
