WebDec 5, 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. WebA data type object (an instance of numpy.dtype class) describes how the bytes in the fixed-size block of memory corresponding to an array item should be interpreted.
