Numpy ndarray.tobytes() function | Python Last Updated : 22 Apr, 2020 Comments Improve Suggest changes Like Article Like Report numpy.ndarray.tobytes() function construct Python bytes containing the raw data bytes in the array. Syntax : numpy.ndarray.tobytes(order='C') Parameters : order : [{‘C’, ‘F’, None}, optional] Order of the data for multidimensional arrays: C, Fortran, or the same as for the original array. Return : Python bytes exhibiting a copy of arr’s raw data.

An example is [(a, int), (b, float)], where each entry in the array is a pair of (int, float). Normally, these attributes are accessed using dictionary lookups such as arr['a'] and arr['b'].

The default, None, results in the view having the same data-type as a. type : Python type, opti 3 min read Numpy ndarray.getfield() function | Python numpy.ndarray.getfield() function return a field of the given array as a certain type.
