np.prod() for product in NumPy - Mini Project: Build & Apply

Calculate Product of Numbers Using np.prod()

📖 Scenario: Imagine you are working in a small business that sells boxes of chocolates. You want to find the total number of chocolates if you multiply the number of chocolates in each box.

🎯 Goal: You will create a list of numbers representing chocolates in each box, then use np.prod() to find the total product of chocolates.

📋 What You'll Learn

Create a numpy array with exact values

Create a variable to hold the product using np.prod()

Print the product value

💡 Why This Matters

🌍 Real World

Calculating total quantities or combined values by multiplying numbers is common in inventory management, finance, and science.

💼 Career

Data scientists often use numpy functions like <code>np.prod()</code> to quickly compute products of data arrays for analysis and modeling.

1

Create a numpy array of chocolates

Import numpy as np and create a numpy array called chocolates with these exact values: 2, 3, 4.

NumPy

# Import numpy and create the chocolates array
# Your code here

Need a hint?

Use np.array() to create the array with the numbers 2, 3, and 4.

2

Calculate the product of chocolates

Create a variable called total_chocolates and set it to the product of all elements in chocolates using np.prod().

NumPy

import numpy as np
chocolates = np.array([2, 3, 4])
# Calculate the product of chocolates using np.prod()
# Your code here

Need a hint?

Use np.prod(chocolates) to multiply all numbers in the array.

3

Print the total product

Write a print() statement to display the value of total_chocolates.

NumPy

import numpy as np
chocolates = np.array([2, 3, 4])
total_chocolates = np.prod(chocolates)
# Print the total_chocolates value
# Your code here

Need a hint?

Use print(total_chocolates) to show the product result.

4

Calculate product for a new array

Create a new numpy array called boxes with values 5, 6, 7. Then calculate the product using np.prod() and store it in total_boxes. Finally, print total_boxes.

NumPy

import numpy as np
chocolates = np.array([2, 3, 4])
total_chocolates = np.prod(chocolates)
print(total_chocolates)
# Create boxes array and calculate product
# Your code here

Need a hint?

Create boxes = np.array([5, 6, 7]), then total_boxes = np.prod(boxes), and print it.
