Quiz
A simple quiz using what we learned about inputs, outputs, and if statements.
def main():
    score = 0
    firstquestion = input("What is 2+2?")
    if firstquestion == "4":
        score += 1
    else:
        score -= 1
    secondquestion = input("What is 1+1?")
    if secondquestion == "2":
        score += 1
    else:
        score -= 1
    if score < 0:
        score = 0
    
    print("You got " + str(score) + " out of 2.")
main()
