assert_data_frame_almost_equal
(left, right)[source]¶Raise AssertionError if pd.DataFrame
objects are not “almost equal”.
State: Experimental as of 0.4.0.
Wrapper of pd.util.testing.assert_frame_equal
. Floating point values
are considered “almost equal” if they are within a threshold defined by
assert_frame_equal
. This wrapper uses a number of
checks that are turned off by default in assert_frame_equal
in order to
perform stricter comparisons (for example, ensuring the index and column
types are the same). It also does not consider empty pd.DataFrame
objects equal if they have a different index.
Other notes:
Index (row) and column ordering must be the same for objects to be equal.
NaNs (np.nan
) in the same locations are considered equal.
This is a helper function intended to be used in unit tests that need to
compare pd.DataFrame
objects.
right (left,) – pd.DataFrame
objects to compare.
AssertionError – If left and right are not “almost equal”.
