Overview

This script will calculate the average of three values. 

Make sure to put in "int" before the raw_input function, since we are
using integers.

# Get three test score
round1 = int(raw_input("Enter score for round 1: "))

round2 = int(raw_input("Enter score for round 2: "))

round3 = int(raw_input("Enter score for round 3: "))
   
# Calculate the average
average = (round1 + round2 + round3) / 3

# Print out the test score
print "the average score is: ", average 

Happy Scripting
