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
Python
x
# Import the NumPy library as npimport numpy as np# Initialize the NumPy arraya = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50])# Remove last element from NumPy arrayb = a[:-1]# Display the array after removing last elementprint(b)Output:
[ 5 10 15 20 25 30 35 40 45]
Method 2: Remove last element from NumPy array using np.arange()
Python
# Import the NumPy library as npimport numpy as np# Initialize the NumPy arraya = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50])# Remove last element from NumPy arrayb = a[np.arange(a.size - 1)]# Display the array after removing last elementprint(b)Output:
[ 5 10 15 20 25 30 35 40 45]
Method 3: Remove last element using np.delete()
Python
# Import the NumPy library as npimport numpy as np# Initialize the NumPy arraya = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50])# Remove last element from NumPy arrayb = np.delete(a, -1)# Display the array after removing last elementprint(b)Output:
[ 5 10 15 20 25 30 35 40 45]
Method 4: Remove last element using np.resize()
Python
# Import the NumPy library as npimport numpy as np# Initialize the NumPy arraya = np.array([5, 10, 15, 20, 25, 30, 35, 40, 45, 50])# Remove last element from NumPy arrayb = np.resize(a, a.size - 1)# Display the array after removing last elementprint(b)Output:
[ 5 10 15 20 25 30 35 40 45]
