numpy.ascontiguousarray() in Python Last Updated : 16 Nov, 2021 Comments Improve Suggest changes Like Article Like Report numpy.ascontiguousarray()function is used when we want to return a contiguous array in memory (C order). Syntax : numpy.ascontiguousarray(arr, dtype=None) Parameters : arr : [array_like] Input data, in any form that can be converted to an array. This includes scalars, lists, lists of tuples, tuples, tuples of tuples, tuples of lists, and ndarrays. dtype : [str or dtype object, optional] Data-type of returned array. Return : ndarray Contiguous array of same shape and content as arr, with type dtype if specified.

It is commonly referred to multidimensional container that holds the same data type. It is the core data structure of the NumPy library and is optimized for numerical and scientific computation in Python. Table of C 2 min read numpy.asscalar() in Python numpy.asscalar() function is used when we want to convert an array of size 1 to its scalar equivalent. Syntax : numpy.asscalar(arr) Parameters : arr : [ndarray] Input array of size 1. Return : Scalar representation of arr. The output data type is the same type returned by the input’s item method. Co 1 min read Python | Numpy MaskedArray.__ne__ numpy.ma.MaskedArray class is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__ne__ operator we can find that which element in an array is not equal to the value which is provided in the parameter. Syntax: numpy.MaskedArray.__ne__ 1 min read numpy.array_str() in Python numpy.array_str()function is used to represent the data of an array as a string. The data in the array is returned as a single string. This function is similar to array_repr, the difference being that array_repr also returns information on the kind of array and its data type. Syntax : numpy.array_st 2 min read Python | Numpy ndarray.__copy__() With the help of Numpy ndarray.__copy__() method, we can make a copy of all the data elements that is present in numpy array. If you change any data element in the copy, it will not affect the original numpy array. Syntax : numpy.__copy__() Return : Copy of all the data elements Example #1 : In this 1 min read numpy.array_repr() in Python numpy.array_repr()function is used to convert an array to a string. Syntax : numpy.array_repr(arr, max_line_width=None, precision=None, suppress_small=None) Parameters : arr : [array_like] Input array. max_line_width : [int, optional] The maximum number of columns the string should span.
