maxframe.dataframe.Series.compare#

Series.compare(other, align_axis: int | str = 1, keep_shape: bool = False, keep_equal: bool = False, result_names: Tuple[str, str] = ('self', 'other'))#

Compare to another Series and show the differences.

Parameters:

  • other (Series) – Object to compare with.

  • align_axis ({0 or 'index', 1 or 'columns'}, default 1) –

    Determine which axis to align the comparison on.

    • 0, or ‘index’Resulting differences are stacked vertically

      with rows drawn alternately from self and other.

    • 1, or ‘columns’Resulting differences are aligned horizontally

      with columns drawn alternately from self and other.

  • keep_shape (bool, default False) – If true, all rows and columns are kept. Otherwise, only the ones with different values are kept.

  • keep_equal (bool, default False) – If true, the result keeps values that are equal. Otherwise, equal values are shown as NaNs.

  • result_names (tuple, default (‘self’, ‘other’)) – Set the dataframes names in the comparison.

Returns:

If axis is 0 or ‘index’ the result will be a Series. The resulting index will be a MultiIndex with ‘self’ and ‘other’ stacked alternately at the inner level.

If axis is 1 or ‘columns’ the result will be a DataFrame. It will have two columns namely ‘self’ and ‘other’.

Return type:

Series or DataFrame

Compare with another DataFrame and show differences.

Notes

Matching NaNs will not appear as a difference.

Examples

>>> import maxframe.dataframe as md
>>> s1 = md.Series(["a", "b", "c", "d", "e"])
>>> s2 = md.Series(["a", "a", "c", "b", "e"])

Align the differences on columns

>>> s1.compare(s2).execute()
  self other
1    b     a
3    d     b

Stack the differences on indices

>>> s1.compare(s2, align_axis=0).execute()
1  self     b
   other    a
3  self     d
   other    b
dtype: object

Keep all original rows

>>> s1.compare(s2, keep_shape=True).execute()
  self other
0  NaN   NaN
1    b     a
2  NaN   NaN
3    d     b
4  NaN   NaN

Keep all original rows and also all original values

>>> s1.compare(s2, keep_shape=True, keep_equal=True).execute()
  self other
0    a     a
1    b     a
2    c     c
3    d     b
4    e     e
