Change output color:

goods.setdefault('count',count)
shopping_car.append(goods)
money -= goods['price']*count
print(' \033[ 31 ;1m currently Purchase \033[0m goods: '+ goods['name'] + ' Purchase quantity: '+ str(count) + ' Current balance is: '+ str(money))---------this The method will change the output color of the currently purchased four words to red,
and change the 31 number to change a series of special effects such as color and shadow. Just give it a try! \033[1m represents the start character \033[0m represents the end character
