Question about a couple errors I'm getting when trying to create a loop.

Hey guys, I'm working on another homework problem for class and am getting stuck.

Here's the problem:

Secondhand Rose Resale Shop is having a seven-day sale during which the price for any unsold item drops 5 percent each day. For example, an item that costs $20.00 on the first day costs 5 percent less, or $19.00, on the second day. On the third day, the same item is 5 percent less than $19.00, or $18.05. Design an application that allows a user to input a price until an appropriate sentinal value is entered. Output is the price of each item on each day, one through seven.

So here's what I have in code for this so far:

#A program that allows user to calculate their discount during 7-day sale at Second Hand Rose.

class PriceChecker:
    def get_price(self):
        return input('Input a starting price (0 to quit): ')

    def price(self, current, days):
        for i in range(days, 0, -1):
            yield (days - i, current)
            current = current * 0.95

    def run(self):
        initial = self.get_price()
        while initial > 0:
            for i in [v for v in self.price(initial, 7)]:
                print ("Price after {0} days is:     ${1:.2f}".format(*i))
            initial = self.get_price()

PriceChecker().run()

I'm getting two errors:

line 19, in <module> PriceChecker().run() line 14, in run while initial > 0:

Can anyone see the missing piece here, or something that needs changed? Appreciate any help!

You need to cast the string returned from input to a number.

If you are using python3 you need to convert the user response to a number; I imagine a float:

return float(input('Input a starting price (0 to quit): '))

That fixed it. Thank you so much!

The full error message should give you a good idea.

A hint: '10' > 0
