#  pandas.core.groupby.DataFrameGroupBy.groups  #

_ property  _ DataFrameGroupBy.  groups  [ [source]
](https://github.com/pandas-
dev/pandas/blob/v2.2.2/pandas/core/groupby/groupby.py#L805-L851) #

    

Dict {group name -> group labels}.

Examples

For SeriesGroupBy:

    
    
    >>> lst = ['a', 'a', 'b']
    >>> ser = pd.Series([1, 2, 3], index=lst)
    >>> ser
    a    1
    a    2
    b    3
    dtype: int64
    >>> ser.groupby(level=0).groups
    {'a': ['a', 'a'], 'b': ['b']}
    

For DataFrameGroupBy:

    
    
    >>> data = [[1, 2, 3], [1, 5, 6], [7, 8, 9]]
    >>> df = pd.DataFrame(data, columns=["a", "b", "c"])
    >>> df
       a  b  c
    0  1  2  3
    1  1  5  6
    2  7  8  9
    >>> df.groupby(by=["a"]).groups
    {1: [0, 1], 7: [2]}
    

For Resampler:

    
    
    >>> ser = pd.Series([1, 2, 3, 4], index=pd.DatetimeIndex(
    ...                 ['2023-01-01', '2023-01-15', '2023-02-01', '2023-02-15']))
    >>> ser
    2023-01-01    1
    2023-01-15    2
    2023-02-01    3
    2023-02-15    4
    dtype: int64
    >>> ser.resample('MS').groups
    {Timestamp('2023-01-01 00:00:00'): 2, Timestamp('2023-02-01 00:00:00'): 4}
