abs() and round() in Python - Mini Project: Build & Apply

Using abs() and round() in Python

📖 Scenario: You are working on a simple weather app that shows temperature differences and rounded temperatures for easy reading.

🎯 Goal: Build a small program that calculates the absolute difference between two temperatures and rounds a temperature value to the nearest whole number.

📋 What You'll Learn

Create variables with exact temperature values

Use the abs() function to find the absolute difference

Use the round() function to round a temperature

Print the results exactly as instructed

💡 Why This Matters

🌍 Real World

Weather apps often show temperature differences and rounded temperatures to help users understand the weather easily.

💼 Career

Knowing how to use abs() and round() is useful in data processing, financial calculations, and any job involving numbers.

1

Create temperature variables

Create two variables called temp_morning and temp_evening with the values -3.7 and 5.2 respectively.

Python

# Create variables temp_morning and temp_evening with values -3.7 and 5.2
# Your code here

Need a hint?

Use the assignment operator = to set the values.

2

Calculate absolute temperature difference

Create a variable called temp_diff and set it to the absolute difference between temp_evening and temp_morning using the abs() function.

Python

temp_morning = -3.7
temp_evening = 5.2
# Calculate absolute difference using abs()
# Your code here

Need a hint?

Use abs() around the subtraction to get a positive result.

3

Round the morning temperature

Create a variable called rounded_morning and set it to the value of temp_morning rounded to the nearest whole number using the round() function.

Python

temp_morning = -3.7
temp_evening = 5.2
temp_diff = abs(temp_evening - temp_morning)
# Round temp_morning using round()
# Your code here

Need a hint?

Use round() with the variable inside the parentheses.

4

Print the results

Print the values of temp_diff and rounded_morning exactly as shown below, each on its own line:
Absolute difference: 8.9
Rounded morning temperature: -4

Python

temp_morning = -3.7
temp_evening = 5.2
temp_diff = abs(temp_evening - temp_morning)
rounded_morning = round(temp_morning)
# Print the results
# Your code here

Need a hint?

Use print() with f-strings to show the variable values.
