Webb5 dec. 2024 · Floats and ints in Python default to using 8 bytes, which is too much for most cases. Merely changing to a 4 bytes variant is a 50% cut on memory use. Ints can be as small as 1 byte, using only 12.5% percent as much memory. Strings, on the other hand, can’t be simplified but can be avoided. WebbNumPy supports a much greater variety of numerical types than Python does. The following table shows different scalar data types defined in NumPy. NumPy numerical types are instances of dtype (data-type) objects, each having unique characteristics. The dtypes are available as np.bool_, np.float32, etc. Data Type Objects (dtype)
