You can remove the last element from the NumPy array with the following methods. If you want to learn Python, I highly recommend reading This Book.
Method 1: Remove last element from NumPy array using slicing
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50]) # Remove last element from NumPy array b = a[:-1] # Display the array after removing last element print(b)
Output:
[ 5 10 15 20 25 30 35 40 45]
Method 2: Remove last element from NumPy array using np.arange()
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50]) # Remove last element from NumPy array b = a[np.arange(a.size - 1)] # Display the array after removing last element print(b)
Output:
[ 5 10 15 20 25 30 35 40 45]
Method 3: Remove last element using np.delete()
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50]) # Remove last element from NumPy array b = np.delete(a, -1) # Display the array after removing last element print(b)
Output:
[ 5 10 15 20 25 30 35 40 45]
Method 4: Remove last element using np.resize()
# Import the NumPy library as np import numpy as np # Initialize the NumPy array a = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50]) # Remove last element from NumPy array b = np.resize(a, a.size - 1) # Display the array after removing last element print(b)
Output:
[ 5 10 15 20 25 30 35 40 45]
