Break statement behavior in Python - Mini Project: Build & Apply

Break Statement Behavior

📖 Scenario: Imagine you are checking a list of daily temperatures to find the first day when the temperature reaches or exceeds a certain limit. Once you find that day, you want to stop checking further days.

🎯 Goal: You will write a program that uses a break statement inside a for loop to stop the loop early when a condition is met.

📋 What You'll Learn

Create a list called temperatures with the exact values: [22, 25, 19, 30, 28, 35, 24]

Create a variable called limit and set it to 30

Use a for loop with the variable temp to go through temperatures

Inside the loop, use an if statement to check if temp is greater than or equal to limit

Use break to stop the loop when the condition is true

After the loop, print the text "First temperature reaching the limit or above: " followed by the value of temp

💡 Why This Matters

🌍 Real World

Checking sensor data or measurements to stop processing once a certain threshold is reached is common in many real-world applications like weather monitoring or quality control.

💼 Career

Understanding how to control loops with break statements is important for writing efficient programs that do not waste time checking unnecessary data.

1

Create the temperature list

Create a list called temperatures with these exact values: [22, 25, 19, 30, 28, 35, 24]

Python

# Create the list temperatures with the given values
# Your code here

Need a hint?

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

2

Set the temperature limit

Create a variable called limit and set it to the number 30

Python

temperatures = [22, 25, 19, 30, 28, 35, 24]
# Create the variable limit and set it to 30
# Your code here

Need a hint?

Use the equals sign = to assign the value 30 to the variable limit.

3

Use a for loop with break

Use a for loop with the variable temp to go through temperatures. Inside the loop, use an if statement to check if temp is greater than or equal to limit. Use break to stop the loop when the condition is true.

Python

temperatures = [22, 25, 19, 30, 28, 35, 24]
limit = 30
# Use a for loop to check each temp in temperatures
# Use if to check if temp >= limit
# Use break to stop the loop when condition is met
# Your code here

Need a hint?

Remember to indent the if and break lines inside the for loop.

4

Print the first temperature reaching the limit

After the loop, write a print statement to display the text "First temperature reaching the limit or above: " followed by the value of temp

Python

temperatures = [22, 25, 19, 30, 28, 35, 24]
limit = 30
for temp in temperatures:
    if temp >= limit:
        break
# Print the result below
# Your code here

Need a hint?

Use print("First temperature reaching the limit or above: ", temp) to show the message and the temperature.
