Variables and Operations
Welcome to your first adventure in Python programming! Imagine stepping onto a sports field, ready to learn the basics. Today, we'll explore variables, naming rules, print statements, and math operations in Python.
Think of variables as lockers where you store your gear. In Python, variables hold data values. For example, if you're tracking a basketball player's performance, you might create a variable called player_score to store the number of points they score in a game:
player_score = 10
Naming variables is like choosing a nickname that reflects your role on the team. Start with a letter or an underscore, and remember that Python is case-sensitive, so score and Score are different. Choose descriptive names like total_distance for clarity. Avoid using reserved words like print or if.
Once you've got your variables, it's time to communicate with your audience. The print() function in Python is your microphone, allowing you to display information. For example:
12345player_name = "John" player_score = 10 print("Player:", player_name) print("Score:", player_score)
In Python, variable names must adhere to specific rules to be valid. Below is a code example that illustrates some common mistakes when naming variables
1st_player = "John" # Invalid: Starts with a number
total-goals = 5 # Invalid: Contains a hyphen
Python is great at handling math operations, similar to calculating a player's average speed. You can add, subtract, multiply, and divide numbers:
goals = 3
assists = 2
total_points = goals + assists
print("Total Points:", total_points)
distance = 100 # in meters
time = 9.58 # in seconds
average_speed = distance / time
print("Average Speed:", average_speed, "m/s")

Your goal is to complete calculate_game_excitement_index function that calculates the Game Excitement Index for an NFL game. This index quantifies the excitement level based on total points scored and how close the game was.
✨ Bonus: See Your Results Visualized! ✨
By finishing the task using the specified steps, you'll unlock a chart that visualizes your results. This chart will provide a clear and engaging representation of the excitement index you've calculated.
Code Instructions:
-
Inputs:
team1_score: The score of the first team.team2_score: The score of the second team.
-
Steps:
- Declare a variable
total_pointsand assign it the sum ofteam1_scoreandteam2_score - Declare a variable
point_differenceand assign it the absolute difference betweenteam1_scoreandteam2_score. Use theabs()function to ensure the result is non-negative. - Create a variable
excitement_indexand calculate it by dividingtotal_pointsby (point_difference+ 1). - Ensure your function returns the
excitement_index.
