#  pandas.Index.get_loc  #

Index.  get_loc  (  _ key  _ )  [ [source]  ](https://github.com/pandas-
dev/pandas/blob/v2.2.2/pandas/core/indexes/base.py#L3777-L3818) #

    

Get integer location, slice or boolean mask for requested label.

Parameters  :

    

**key** label

    
Returns  :

    

int if unique index, slice if monotonic index, else mask

    

Examples

    
    
    >>> unique_index = pd.Index(list('abc'))
    >>> unique_index.get_loc('b')
    1
    
    
    
    >>> monotonic_index = pd.Index(list('abbc'))
    >>> monotonic_index.get_loc('b')
    slice(1, 3, None)
    
    
    
    >>> non_monotonic_index = pd.Index(list('abcb'))
    >>> non_monotonic_index.get_loc('b')
    array([False,  True, False,  True])
