Actually, the numbers of days can be only five. Your idea is great but I'd have to proggram all over again, because the structure I used was

day = int(raw_input("Type the day: "))

while day == 1:

    work = str(raw_input("Type if it's work or exit "))

    while work == "no":
        day1["D"] += 1
        break

    while work == "yes":
        rotation = raw_input("Type the rotation or exit: ")
        while rotation != "exit":
            if float(rotation) > 10:
                day1["C"] += 1
                break

            elif float(rotation) > 2 and float(rotation) <= 10:
                time = float(raw_input("What was the answer time? "))
                if time > 3 :
                    day1["B"] += 1
                    break
                else:
                    day1["A"] += 1
                    break
            elif float(rotacoes) <2:
                day1["A"] += 1
                break
        if rotation == "exit":
            break

    if work == "exit":
        day = int(raw_input("Type the day: "))
        break

And I did that 5 times, for each day. Anyway, I'll try to do what you said
