Add robotics-themed functions for drone operations

[Copilot]

This PR implements two reusable robotics-themed functions in 03_functions.py for the RobotX Workshops Python coding examples collection.

Changes

Created 03_functions.py with the following functions:

1. calculate_distance(speed, time)

Calculates the distance traveled by a drone given its speed and flight time.

Parameters:

• speed (float): Speed in meters per second
• time (float): Time in seconds

Returns: Distance traveled in meters

Example:

distance = calculate_distance(5.0, 10.0)
print(distance)  # Output: 50.0

2. format_sensor_data(x, y, z)

Formats sensor position data into a human-readable string representation.

Parameters:

• x, y, z (float): Coordinate values

Returns: Formatted string like "Position: (x=10, y=20, z=5)"

Example:

formatted = format_sensor_data(10, 20, 5)
print(formatted)  # Output: "Position: (x=10, y=20, z=5)"

Demo Output

When running python3 03_functions.py, the following demonstration output is displayed:

Example 1: Distance traveled
  Speed: 5.0 m/s
  Time: 10.0 s
  Distance: 50.0 m

Example 2: Sensor data formatting
  Raw coordinates: x=10, y=20, z=5
  Formatted: Position: (x=10, y=20, z=5)

Both functions include comprehensive docstrings with parameter descriptions, return types, and usage examples following Python best practices.

Original prompt

Create Themed Functions
This prompt focuses on building reusable code blocks (functions) that directly relate to drone operations.

In 03_functions.py, create two robotics-themed functions with clear docstrings.

1. A function calculate_distance(speed, time) that returns the distance traveled.
2. A function format_sensor_data(x, y, z) that returns a formatted string like "Position: (x=10, y=20, z=5)".
   Show an example of calling each function and printing the result.
