#  pandas.Index.is_  #

_ final  _ Index.  is_  (  _ other  _ )  [ [source]
](https://github.com/pandas-
dev/pandas/blob/v2.2.2/pandas/core/indexes/base.py#L791-L829) #

    

More flexible, faster check like ` is  ` but that works through views.

Note: this is _not_ the same as ` Index.identical()  ` , which checks that
metadata is also the same.

Parameters  :

    

**other** object

    

Other object to compare against.

Returns  :

    

bool

    

True if both have same underlying data, False otherwise.

See also

[ ` Index.identical  ` ](pandas.Index.identical.html#pandas.Index.identical
"pandas.Index.identical")

    

Works like ` Index.is_  ` but also checks metadata.

Examples

    
    
    >>> idx1 = pd.Index(['1', '2', '3'])
    >>> idx1.is_(idx1.view())
    True
    
    
    
    >>> idx1.is_(idx1.copy())
    False
