Calculating the dot product of NumPy arrays

Python Pandas Numpy: Exercise-20 with Solution

Calculate the dot product of two NumPy arrays.

Sample Solution-1:

Python Code:

import numpy as np

# Create two NumPy arrays
array1 = np.array([1, 2, 3])
array2 = np.array([4, 5, 6])

# Calculate the dot product
dot_product = np.dot(array1, array2)

# Display the result
print(dot_product)

Output:

32

Sample Solution-2:

Python Code:

import numpy as np

# Create two NumPy arrays
array1 = np.array([1, 2, 3])
array2 = np.array([4, 5, 6])

# Calculate the dot product
dot_product = array1 @ array2

# Display the result
print(dot_product)

Output:

21
