Say we want to keep only the rows whose values in column colB are greater than 200 and values in column colD are less or equal to 50. Like numpy.ndarray and pandas.DataFrame, you need to use &, |, ~, and parentheses (). According to your error trace back, It's definitely pd.NA(pandas._libs.missing.NA) that causes the bug. 1 bool int 0 False True a_single = np.array( [0]) b_single = np.array( [1]) c_single = np.array( [2]) print(bool(a_single)) # False print(bool(b_single)) # True print(bool(c_single)) # True I'm going to move this off 1.0.0, I think that .searchsorted(NA) not working will be a known limitation. You are providing a value and an iterable. The above expression will fail with the following error: The error is raised because you chain multiple conditions using logical operators (such as and, or, not) resulting in ambiguous logic since the returned results are column-based for each individual condition specified. Youll also get full access to every story on Medium. This would require some care to do in a way that minimizes any performance hits though. This happens in an if -statement or when using the boolean operations: and, or, and not. Changed in version 1.0.2.

Have you find out what causes the riskiness while calling numpy.count_nonzero() with a pandas.Series? scipy : 1.3.1 Also in my example, there are no missing values in the series. Takeaway: When the source column contains null values or non-boolean values such as floats like 1.0 , applying the Pandas 'bool' dtype may . Have a question about this project? How to react to a students panic attack in an oral exam? The searchsorted call here is to numpy but we have our own internal algos.searchsorted that we could make mask-aware, and then just ensure that all of our internal searchsorted calls go through algos.searchsorted and not directly to numpy. For instance, to reproduce the error in the Shell : Since the actual value of an NA is unknown, it is ambiguous to convert The text was updated successfully, but these errors were encountered: I was experimenting also building the explorer files in other formats beyond CSV. DataFrame has gained the .asof() method to return the last non-NaN values according to the selected subset In [1]: s = pd.Series( [1, 2, 3]) In [2]: mask = pd.array( [True, False, pd.NA], dtype="boolean") In [3]: s[mask] Out [3]: 0 1 dtype: int64 If you would prefer to keep the NA values you can manually fill them with fillna (True). Of course, parentheses are also acceptable. . If you want to cover whole elements, use axis=None. Because in principle, pd.cut simply propagates NAs in the input to the output, so they don't need to be passed through the full binning (for which searchsorted is used).
