numpy.ravel(a, order='C') [source] #. Return a contiguous flattened array. A 1-D array, containing the elements of the input, is returned. A copy is made only if needed. As of NumPy 1.10, the returned array will have the same type as the input array. (for example, a masked array will be returned for a masked array input) Parameters: aarray_like.

Suppose we have a 2D Numpy array, Output: Let’s generate a flattened 1D view of this 2D numpy array using ravel() function, Output: We didn’t provide any order parameter therefore the default value of order parameter ‘C’ was used and elements from the 2D array were read row by row.
ndarray.ravel() accepts an optional parameter order. It can be ‘C’ or ‘F’ or ‘A’, but the default value is ‘C’. It tells the order in which items from input numpy array will be used, 1. ‘C’: Read items from array row wise i.e. using C-like index order. 2. ‘F’: Read items from array column wise i.e. using Fortran-like index order. 3. ‘A’: Read items...
numpy.ravel() expects an array like parameter, from which it will create a flattened view. So, instead of a numpy array we can also pass list or list of listsin the ravel() function directly. Suppose we have a list of lists, Now let’s create a flattened numpy array from this list of list, Output: We can also convert this flattened numpy array to a ...
Summary: in this tutorial, you’ll learn how to use the NumPy ravel() to return a contiguous flattened array. The ravel() function accepts an array and returns a 1-D array containing the elements of the input array: In this syntax: a is a numpy array. It can be any array-like object e.g., a list.
The ravel() method flattens a NumPy array without changing its data. Example. import numpy as np. array1 = np.array([[0, 1], [2, 3]]) # flatten an array . array2 = np.ravel(array1) print(array2) # Output : [0 1 2 3] ravel () Syntax. The syntax of ravel() is: numpy.ravel(array, order) ravel () Arguments. The ravel() method takes two arguments:
Return a contiguous flattened array. A 1-D array, containing the elements of the input, is returned. A copy is made only if needed. As of NumPy 1.10, the returned array will have the same type as the input array. (for example, a masked array will be returned for a masked array input) Input array.
Feb 2, 2024 · In NumPy, to flatten an array (ndarray), use the np.ravel() function, or the ravel() and flatten() methods of ndarray.
