=== Putting it all together with a math game ===
<source lang="Python">
"""
It uses the concepts that we just reviewed (random, range, input, and while) to build a math guessing game.
random.choice, range, input, while, and join.

This program asks people to add together two random numbers between 1 and 1000, and keep asking them new questions as long as they gave the answer right to the previous math problem. Once they give an incorrect answer, it prints out how many they got right, and also prints all their correct responses using join.

true_answer = 0
your_answer = 0
while true_answer == your_answer:
    num1 = random.choice(numbers_to_add)
    num2 = random.choice(numbers_to_add)
