youre so smart, i cant figure out the foods.append(food) i cant fix it, it means my knowledge in python is still off
You should give flow to the price +=
You forgot to put flow in the price.
6:43 lol you type so fast XD
Don't stop bro!!! Greate videos
What's the purpose of the f in the beginning on the string?
how do you declare a list? ive atempted to make something similar to this but my lists are getting the undeclared error
Ok, so I tried making this output look better, but failed at displaying the cart with proper alignment, can anyone help?
I think this line of the code needs to be modified, print(f"{i}. {food.capitalize()} x {quantity:<13}", end=""), but I maybe (I am) wrong.
# Shopping Cart
foods = []
prices = []
quantities = []
total = 0
print("Enter your food products. Press Enter to quit. ")
i = 1
while True:
food = input(f"{i}. ")
if food == "":
break
else:
price = float(input(f"Price of {food}: "))
quantity = int(input(f"Number of {food}: "))
foods.append(food)
prices.append(price)
quantities.append(quantity)
i += 1
print("——— YOUR CART ———")
i = 1
if len(foods) == 0:
text = "Your cart is empty."
print(f"{text:^19}")
else:
for food in foods:
price = prices[i – 1]
quantity = quantities[i – 1]
print(f"{i}. {food.capitalize()} x {quantity:<13}", end="")
print(f"${price * quantity}")
total += price * quantity
i += 1
print("—————————–")
if not len(foods) == 0:
print(f"Your total is: ${total}")

Iโm so confused, Iโve got everything typed exactly as it is on the video but when I get to the price it throws an error and tells me โstrโ object has no attribute โappendโ why clue what I am doing wrong?
i love your videos
Surprisingly, I am getting an " unsupported operand type(s) for +: int and list" error. Here is my code
foods = []
prices = []
total = 0
while True:
food = input(" Enter a food to buy('q' to quit): ")
if food.lower() == "q":
break
else:
price = float(input(f"Enter the price of a {food}: Kshs "))
foods.append(food)
prices.append(prices)
print ("—–Your Cart —–")
for food in foods:
print (food, end= ' ')
for price in prices:
total += price
print(f"Your total is Kshs{total}")
What could be wrong here?
