modin.pandas.Series.equals¶

Series.equals(other)[source]¶

Test whether two series contain the same elements.

This function allows two Series to be compared against each other to see if they have the same shape and elements. NaNs in the same location are considered equal.

The row/column index do not need to have the same type, as long as the values are considered equal. Corresponding columns and index must be of the same dtype. Note: int variants (int8, int16 etc) are considered equal dtype i.e int8 == int16. Similarly, float variants (float32, float64 etc) are considered equal dtype.

Parameters:

other (Series) – The other Series to be compared with the first.

Returns:

True if all elements are the same in both series, False otherwise.

Return type:

bool

Series.eq

Compare two Series objects of the same length and return a Series where each element is True if the element in each Series is equal, False otherwise.

DataFrame.eq

Compare two DataFrame objects of the same shape and return a DataFrame where each element is True if the respective element in each DataFrame is equal, False otherwise.

testing.assert_series_equal

Raises an AssertionError if left and right are not equal. Provides an easy interface to ignore inequality in dtypes, indexes and precision among others.

testing.assert_frame_equal

Like assert_series_equal, but targets DataFrames.

numpy.array_equal

Return True if two arrays have the same shape and elements, False otherwise.

Examples

>>> series = pd.Series([1, 2, 3], name=99)
>>> series
0    1
1    2
2    3
Name: 99, dtype: int64

Copy

Series ‘series’ and ‘exactly_equal’ have the same types and values for their elements and names, which will return True.

>>> exactly_equal = pd.Series([1, 2, 3], name=99)
>>> exactly_equal
0    1
1    2
2    3
Name: 99, dtype: int64
>>> series.equals(exactly_equal)
True

Copy

Series ‘series’ and ‘different_column_type’ have the same element types and values, but have different types for names, which will still return True.

>>> different_column_type = pd.Series([1, 2, 3], name=99.0)
>>> different_column_type
0    1
1    2
2    3
Name: 99.0, dtype: int64
>>> series.equals(different_column_type)
True

Copy

Series ‘series’ and ‘different_data_type’ have different types for the same values for their elements, and will return False even though their names are the same values and types.

>>> different_data_type = pd.Series([1.0, 2.0, 3.0], name=99)
>>> different_data_type
0    1.0
1    2.0
2    3.0
Name: 99, dtype: float64
>>> series.equals(different_data_type)
False
