How to use flipud function to Reverse a Numpy array In Python
The numpy.flipud() function flips the array(entries in each column) in up-down direction, shape preserved.
Python3
import numpy as np # initialising numpy array ini_array = np.array([ 1 , 2 , 3 , 6 , 4 , 5 ]) # printing initial ini_array print ( "initial array" , str (ini_array)) # printing type of ini_array print ( "type of ini_array" , type (ini_array)) # using flipud method to reverse res = np.flipud(ini_array) # printing result print ( "final array" , str (res)) |
Output:
initial array [1 2 3 6 4 5] type of ini_array <class 'numpy.ndarray'> final array [5 4 6 3 2 1]
Python | Reverse a numpy array
As we know Numpy is a general-purpose array-processing package that provides a high-performance multidimensional array object, and tools for working with these arrays. Let’s discuss how can we reverse a Numpy array.
