Looping help

[Wilson1218]

Hello, I need help looping some code. The problem is that there are many lists that I have to .append to and they are all named similarly, but different. Can I loop this code?
Note: All names of lists must remain the same.
Note 2: per_no is a count in a loop that this code is in.

        yeild1 = float(input("Yield 1"))
        yeild2 = float(input("Yield 2"))
        if per_no == 1:
            per1.append(yeild1)
            per1.append(yeild2)
            if day == 1:
                day1.append(yeild1)
                day1.append(yeild2)
            elif day == 2:
                day2.append(yeild1)
                day2.append(yeild2)
            elif day == 3:
                day3.append(yeild1)
                day3.append(yeild2)
            elif day == 4:
                day4.append(yeild1)
                day4.append(yeild2)
            elif day == 5:
                day5.append(yeild1)
                day5.append(yeild2)
            elif day == 6:
                day6.append(yeild1)
                day6.append(yeild2)
            elif day == 7:
                day7.append(yeild1)
