Comparison operations in NumPy - Mini Project: Build & Apply

Comparison operations

📖 Scenario: You work in a store that tracks daily sales numbers. You want to find which days had sales above a certain target.

🎯 Goal: Build a small program using numpy to compare daily sales numbers against a sales target and find which days met or exceeded the target.

📋 What You'll Learn

Use numpy arrays to store sales data

Create a sales target variable

Use comparison operations to find days with sales >= target

Print the boolean array showing which days met the target

💡 Why This Matters

🌍 Real World

Stores and businesses often compare daily sales or performance numbers against targets to see which days did well.

💼 Career

Data analysts and scientists use comparison operations to filter and analyze data quickly and efficiently.

1

Create the sales data array

Create a numpy array called sales with these exact daily sales numbers: 120, 85, 90, 150, 110.

NumPy

import numpy as np
# Create the numpy array called sales with the given numbers
# Your code here

Need a hint?

Use np.array([...]) to create the array with the exact numbers.

2

Set the sales target

Create a variable called target and set it to the integer 100.

NumPy

import numpy as np
sales = np.array([120, 85, 90, 150, 110])
# Create the variable target and set it to 100
# Your code here

Need a hint?

Just assign the number 100 to the variable target.

3

Compare sales to the target

Create a variable called above_target that stores the result of comparing sales to target using the >= operator.

NumPy

import numpy as np
sales = np.array([120, 85, 90, 150, 110])
target = 100
# Create above_target using sales >= target
# Your code here

Need a hint?

Use the >= operator between the sales array and the target variable.

4

Print the comparison result

Print the variable above_target to show which days had sales greater than or equal to the target.

NumPy

import numpy as np
sales = np.array([120, 85, 90, 150, 110])
target = 100
above_target = sales >= target
# Print above_target
# Your code here

Need a hint?

Use print(above_target) to display the boolean array.
