WebMay 21, 2024 · As a default np.array assigns the best common dtype to the whole array, in this case, a string. Once created that dtype is fixed, and can't be changed by simple assignment. Consider structured arrays or object dtype arrays if you must mix floats and strings. But beware that those come with an increased processing cost. – WebApr 15, 2016 · On a 32-bit system, default types will be 32-bit. There is no way to change the default short of re-compiling numpy with a different system C header.
