Remember that the English words and and or are often used in the form if A and B:, and the symbols & and | are used in other mathematical operations. Contributor. Furthermore, it provides a valuable piece of advise: "This also means that pd.NA cannot be used in a context where it is evaluated to a boolean, such as if condition: where condition can potentially be pd.NA. It would be indeed be nice to at least solve things like pd.cut for 1.0, as this was working for Int64 dtype before. privacy statement. For example, if the element is an integer int, it is False if it is 0 and True otherwise. 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. I didn't figure out if this is a bug in the way pd passed values to np, or a bug in np.count_nonzero, or bug in pd.NA itself, so I haven't reported this bug yet. Use a.empty, a.bool(), a.item(), a.any() or a.all() really means? matplotlib : 3.1.1 Is a hot staple gun good enough for interior switch repair? 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 Pandas follows the numpy convention of raising an error when you try to convert something to a bool. We probably need to make a "mask-aware" version of our algorithms like cut. pandas raises unexpected TypeError, but we support treating NaN as the smallest value. The fix for cut(IntegerArray) is targeted for 1.0.0. Sign up for a free GitHub account to open an issue and contact its maintainers and the community.

We reproduced the error in an attempt to better understand why the error is raised in the first place and additionally, we discussed how to deal with it using Pythons bitwise operators or NumPys logical operators methods. When combining multiple conditions with & or |, it is necessary to enclose each conditional expression in parentheses (). . One option for a "quick" fix might be to convert the integer array to a float array at the beginning of the cut (and related) method. This would require some care to do in a way that minimizes any performance hits though. The following raises an error: TypeError: boolean value of NA is ambiguous Furthermore, it provides a valuable piece of advise: "This also means that pd.NA cannot be used in a context where it is evaluated to a boolean, such as if condition: . Sign in You are providing a value and an iterable. By clicking Sign up for GitHub, you agree to our terms of service and pytables : None In NumPy and pandas, using numpy.ndarray or pandas.DataFrame in conditional expressions or and, or operations may raise an error. Every time you run an expression with operands and operators, the Python tries to evaluate individual values to boolean. Evaluating numpy.ndarray as a bool value raises an error. If the number of elements is one or zero, as indicated by the error message "more than one element", no error is raised. Version information is essential in reproducing and resolving bugs.
