polars.testing.assert_series_not_equal( left: Series, right: Series, *, check_dtype: bool = True, check_names: bool = True, check_exact: bool = False, rtol: float = 1e-05, atol: float = 1e-08, categorical_as_str: bool = False, ) → None[source]#

Assert that the left and right Series are not equal.

This function is intended for use in unit tests.

Parameters:

left: The first Series to compare.
right: The second Series to compare.
check_dtype: Require data types to match.
check_names: Require names to match.
check_exact: Require float values to match exactly. If set to False, values are considered equal when within tolerance of each other (see rtol and atol). Only affects columns with a Float data type.
rtol: Relative tolerance for inexact checking, given as a fraction of the values in right.
atol: Absolute tolerance for inexact checking.
categorical_as_str: Cast categorical columns to string before comparing. Enabling this helps compare columns that do not share the same string cache.
