You can reverse an array in Python with any of the following methods. If you want to learn Python, I highly recommend reading This Book.
Method 1: Reverse an array using Slicing
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([10, 20, 30, 40, 50]) # Reverse an Array b = a[::-1] # Display the Reverse Array print(b)
Output:
[50 40 30 20 10]
Method 2: Reverse an array using np.flip()
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([10, 20, 30, 40, 50]) # Reverse an Array b = np.flip(a) # Display the Reverse Array print(b)
Output:
[50 40 30 20 10]
Method 3: Reverse an array using np.flipud()
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([10, 20, 30, 40, 50]) # Reverse an Array b = np.flipud(a) # Display the Reverse Array print(b)
Output:
[50 40 30 20 10]
