Random choice from array in NumPy - Mini Project: Build & Apply

Random Choice from Array with NumPy

📖 Scenario: You are working with a list of fruits in a grocery store. You want to randomly select a fruit to feature as the "Fruit of the Day" on the store's website.

🎯 Goal: Build a small program that uses NumPy to randomly select one fruit from a list of fruits.

📋 What You'll Learn

Create a NumPy array with the exact fruits given

Create a variable to hold the number of fruits

Use NumPy's random choice function to select one fruit randomly

Print the selected fruit

💡 Why This Matters

🌍 Real World

Random selection is useful in many real-world cases like picking a winner in a contest, sampling data, or choosing a random product to promote.

💼 Career

Data scientists often use random sampling to analyze data subsets or to create randomized experiments.

1

Create a NumPy array of fruits

Import NumPy as np and create a NumPy array called fruits with these exact values: 'apple', 'banana', 'cherry', 'date', 'elderberry'.

NumPy

import numpy as np
# Create the NumPy array called fruits with the exact fruit names
# Your code here

Need a hint?

Use np.array([...]) to create the array.

2

Create a variable for the number of fruits

Create a variable called num_fruits that stores the number of fruits in the fruits array using the len() function.

NumPy

import numpy as np
fruits = np.array(['apple', 'banana', 'cherry', 'date', 'elderberry'])
# Create num_fruits to hold the length of fruits
# Your code here

Need a hint?

Use len(fruits) to get the number of items.

3

Select a random fruit using NumPy

Use np.random.choice() to select one random fruit from the fruits array and store it in a variable called random_fruit.

NumPy

import numpy as np
fruits = np.array(['apple', 'banana', 'cherry', 'date', 'elderberry'])
num_fruits = len(fruits)
# Select one random fruit from fruits and store in random_fruit
# Your code here

Need a hint?

Use np.random.choice(fruits) to pick one item randomly.

4

Print the randomly selected fruit

Print the value stored in random_fruit to display the randomly selected fruit.

NumPy

import numpy as np
fruits = np.array(['apple', 'banana', 'cherry', 'date', 'elderberry'])
num_fruits = len(fruits)
random_fruit = np.random.choice(fruits)
# Print the random_fruit
# Your code here

Need a hint?

Use print(random_fruit) to show the chosen fruit.
