Trying to have my python program add the total values after the loop, but it outputs the final values

Question

#Variables
total = 0
day = 0
car = 0

while day <= 4:
  day += 1

  if day <= 5:
    print('Cars sold on day', day, end = ': ',)
    carSold = int(input(''))

    for amount in range(carSold):
      print('Selling price of car', amount + 1, end = ':\t')
      price = int(input('$'))

  if day >= 5:
    total += price
    car += carSold
    print('\nYou sold', car, 'cars for a total of $', format(total,',.2f'))

The different configurations I have tried all either add after every input or just the last value.

You added values to total and car only at the last day, while the code below is adding values everyday.

#Variables
total = 0
car = 0

for day in range(1, 6):
    carSold = int(input('Cars sold on day {}: '.format(day)))
    car += carSold

    for amount in range(carSold):
        total += int(input('Selling price of car {}: $'.format(amount+1)))

    if day == 5:
        print('\nYou sold', car, 'cars for a total of $', format(total,',.2f'))

You are the bomb.com. Can you explain what the format for day and amount+1 does?

They replace {} to input argument.(docs.python.org/3.6/library/string.html#format-string-syntax)

EDITED: Writing concise code is very important in Python, and so is error checking since it is very easy to spawn an error by typing anything other than a number:

total = 0
day = 0
car = 0
carSold = 0
lastsold = 0


while day <= 4:
    day += 1
    try:
        if day <= 5:
            lastsold += int(input('Cars sold on day %i: '%day))
            carSold += lastsold

        for amount in range(carSold):
            total += int(input('Selling price of car %i: $'%(amount+1)))
    except:
        day -= 1
        carSold -= lastsold
        continue
    lastsold = 0

    if day >= 5:
        print('\nYou sold %i cars for a total of $%.2f'%(car,total))
