What are some tools or methods I can purchase to trace a water leak? You are providing a value and an iterable. 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. On the other hand, & and | are used for bitwise operations for integer values and element-wise operations for numpy.ndarray as described above, and set operations for set. Apparently regular max can not deal with arrays (easily). ^ (XOR) is also available. Pandas follows the numpy convention of raising an error when you try to convert something to a bool. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Note that comparison operations on many objects other than numpy.ndarray return True or False.

Longer term: I don't think it is easy to fix the searchsorted directly, as here it is a numpy call, where the passed integer array gets converted to an object numpy array (at least if we don't want to change the coercing behaviour of IntegerArray and the comparison and boolean behaviour of pd.NA). What's the difference between a power rail and a signal line? Also, you take into account it is an experimental feature, hence it shouldn't be used for anything but experimenting: Warning Experimental: the behaviour of pd.NA can still change without warning. 2.
