Search and rescue assistance in Drone Programming - Mini Project: Build & Apply

Search and Rescue Assistance

📖 Scenario: You are programming a drone to help in search and rescue missions. The drone needs to scan an area and identify locations where people might be trapped. Each location has a signal strength indicating the likelihood of a person being there.

🎯 Goal: Build a program that stores locations with their signal strengths, sets a threshold to decide which locations need rescue, filters those locations, and then prints the list of locations that require immediate attention.

📋 What You'll Learn

Create a dictionary called locations with exact keys and signal strength values

Create a variable called threshold with the exact value 70

Use a dictionary comprehension to create a new dictionary called rescue_needed with locations having signal strength greater than or equal to threshold

Print the rescue_needed dictionary

💡 Why This Matters

🌍 Real World

Drones help rescue teams by quickly identifying areas where people might be trapped using signal strengths or sensor data.

💼 Career

Understanding how to filter and process data is essential for programming drones and other autonomous devices in emergency response roles.

1

DATA SETUP: Create the locations dictionary

Create a dictionary called locations with these exact entries: 'Zone A': 65, 'Zone B': 80, 'Zone C': 55, 'Zone D': 90, 'Zone E': 40

Drone Programming

# Create the locations dictionary with signal strengths
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys as zone names and values as signal strengths.

2

CONFIGURATION: Set the signal strength threshold

Create a variable called threshold and set it to the integer 70

Drone Programming

locations = {'Zone A': 65, 'Zone B': 80, 'Zone C': 55, 'Zone D': 90, 'Zone E': 40}
# Set the threshold value for rescue
# Your code here

Need a hint?

Just assign the number 70 to the variable threshold.

3

CORE LOGIC: Filter locations needing rescue

Use a dictionary comprehension to create a new dictionary called rescue_needed that includes only the locations from locations where the signal strength is greater than or equal to threshold

Drone Programming

locations = {'Zone A': 65, 'Zone B': 80, 'Zone C': 55, 'Zone D': 90, 'Zone E': 40}
threshold = 70
# Create rescue_needed dictionary with locations having signal >= threshold
# Your code here

Need a hint?

Use {zone: strength for zone, strength in locations.items() if strength >= threshold} to filter the dictionary.

4

OUTPUT: Print the rescue_needed dictionary

Write a print statement to display the rescue_needed dictionary

Drone Programming

locations = {'Zone A': 65, 'Zone B': 80, 'Zone C': 55, 'Zone D': 90, 'Zone E': 40}
threshold = 70
rescue_needed = {zone: strength for zone, strength in locations.items() if strength >= threshold}
# Print the rescue_needed dictionary
# Your code here

Need a hint?

Use print(rescue_needed) to show the filtered dictionary.
