Bad Input on Line Without an Input

Good afternoon Stack Overflow community. I was working on a fighting sim as a side project and I was stopped short by an input error on line 11. The only problem seems to be that line 11 doesn't have an input statement. I'm unsure of what is causing this:

#Fighting Simulator

    tutorial = input("Would you like a brief rundown of how to play? (Y/N): ")    
    if tutorial == "Y":

    else:
        chosen = False
        while chosen == False:
            maxstats = 25
            fightername = input("\rEnter your fighter's name: ")
            print("Choose your fighter's stats. Total stat points cannot exceed 25.")
            strength = eval(input("Enter a value between 1 and 10 for your fighter's strength: "))
            blocking = eval(input("Enter a value between 1 and 10 for your fighter's blocking: "))
            quickness = eval(input("Enter a value between 1 and 10 for your fighter's quickness: "))    
            luck = eval(input("Enter a value between 1 and 10 for your fighter's luck: "))
            deception = eval(input("Enter a value between 1 and 10 for your fighter's deceptiveness: "))              
            totalstats = strength+blocking+quickness+luck+deception
