WebNov 2, 2014 · Data-types can be used as functions to convert python numbers to array scalars (see the array scalar section for an explanation), python sequences of numbers to arrays of that type, or as arguments to the dtype keyword that many numpy functions or methods accept. Some examples: WebMay 21, 2024 · As a default np.array assigns the best common dtype to the whole array, in this case, a string.
