Finding Maximum and Minimum Values with max() and min()

📖 Scenario: You work in a small store and want to find the most expensive and cheapest items in your product list.

🎯 Goal: Build a simple program that finds the maximum and minimum prices from a list of product prices using max() and min().

📋 What You'll Learn

Create a list of product prices

Create variables to hold the maximum and minimum prices

Use max() and min() functions to find the highest and lowest prices

Print the maximum and minimum prices

💡 Why This Matters

🌍 Real World

Stores and businesses often need to find the highest and lowest prices or values quickly to make decisions.

💼 Career

Knowing how to use max() and min() helps in data analysis, reporting, and making smart choices in programming jobs.

1

Create a list of product prices

Create a list called prices with these exact values: 15.99, 23.50, 9.99, 5.49, and 12.00.

Python

# Create the list of prices
# Your code here

Need a hint?

Use square brackets [] to create a list and separate values with commas.

2

Create variables for max and min prices

Create two variables called max_price and min_price and set both to 0.

Python

prices = [15.99, 23.50, 9.99, 5.49, 12.00]
# Create max_price and min_price variables and set them to 0
# Your code here

Need a hint?

Use simple assignment like variable = 0.

3

Find the maximum and minimum prices using max() and min()

Use the max() function on prices and assign the result to max_price. Then use the min() function on prices and assign the result to min_price.

Python

prices = [15.99, 23.50, 9.99, 5.49, 12.00]
max_price = 0
min_price = 0
# Use max() and min() on prices and assign to max_price and min_price
# Your code here

Need a hint?

Use max_price = max(prices) and min_price = min(prices).

4

Print the maximum and minimum prices

Print the values of max_price and min_price exactly as shown: print(max_price) and print(min_price).

Python

prices = [15.99, 23.50, 9.99, 5.49, 12.00]
max_price = max(prices)
min_price = min(prices)
# Print max_price and min_price
# Your code here

Need a hint?

Use two print statements: print(max_price) and print(min_price).
