NumPy ndarray.tolist() Method | Convert NumPy Array to List Last Updated : 05 Feb, 2024 Comments Improve Suggest changes Like Article Like Report The ndarray.tolist() method converts a NumPy array into a nested Python list. It returns the array as an a.ndim-levels deep nested list of Python scalars. Data items are converted to the nearest compatible built-in Python type. Example Python3 import numpy as np gfg = np.array([1, 2, 3, 4, 5]) print(gfg.tolist()) Output[1, 2, 3, 4, 5] SyntaxSyntax: ndarray.tolist() Parameters: none Returns: The possibly nested list of array elements. How to Convert NumPy Array to Python ListTo convert a NumPy array to a Python list we use ndarray.tolist method of NumPy library in Python. It returns a copy of the array data as a Python list (Nested list in case of a multi-dimensional array). Let us understand it better with an example: Example:In this example, we can see that by using ndarray.tolist() method, we can have the list of data items in ndarray. Python3 # import the important module in python import numpy as np # make an array with numpy gfg = np.array([[1, 2, 3, 4, 5], [6, 5, 4, 3, 2]]) # applying ndarray.tolist() method print(gfg.tolist()) Output[[1, 2, 3, 4, 5], [6, 5, 4, 3, 2]] Comment More infoAdvertise with us Next Article NumPy ndarray.tolist() Method | Convert NumPy Array to List J Jitender_1998 Follow Improve Article Tags : Python Python-numpy Python numpy-ndarray Practice Tags : python Similar Reads Convert Python List to numpy Arrays NumPy arrays are more efficient than Python lists, especially for numerical operations on large datasets.

In Python, there are different ways to achieve this conversion, depending on the structure and organization of the resulting array.For example, consider a dic 3 min read How to convert NumPy array to dictionary in Python? The following article explains how to convert numpy array to dictionary in Python. Array in Numpy is a table of elements (usually numbers), all of the same type, indexed by a tuple of positive integers. In Numpy, number of dimensions of the array is called rank of the array. A tuple of integers givi 3 min read NumPy ndarray.transpose() Method | Find Transpose of the NumPy Array The ndarray.transpose() function returns a view of the array with axes transposed. For a 1-D array, this has no effect, as a transposed vector is simply the same vector.For a 2-D array, this is a standard matrix transpose.For an n-D array, if axes are given, their order indicates how the axes are pe 2 min read How to Convert NumPy Matrix to Array In NumPy, a matrix is essentially a two-dimensional NumPy array with a special subclass. In this article, we will see how we can convert NumPy Matrix to Array. Also, we will see different ways to convert NumPy Matrix to Array.
