On master trying to use pd.NA as an input to searchsorted fails, and trying to use the searchsorted of an array containing pd.NA also fails: Note that the np.nan equivalent works fine: This has downstream effects on anything that relies on searchsorted, e.g. Error builtins.TypeError: boolean value of NA is ambiguous is raised where there is a missing value in a boolean expression. In addition, you can get the total number of elements with the size attribute and check if numpy.ndarray is empty or not with it. Your home for data science. As it seems by looking at the source code this is intentional as NA isnt really True or False, its boolean value is ambiguous as it is a "missing value indicator".

For example, if a list is empty (number of elements is 0), it is evaluated as False, otherwise as True. Currently while upgrading several dependencies (pandas 1.3.1, numpy 1.23.5, etc.) Since the actual value of an NA is unknown, it is ambiguous to convert NA to a boolean value. BUG: pd.NA is not compatible with searchsorted, Unexpected behavior in cut() with nullable Int64 dtype, ROADMAP: Consistent missing value handling with new NA scalar.
