I am implementing pset3 Felipe’s Taqueria in cs50p; but I have noticed something odd in the variables after running debug

Question

My code seems to work perfectly except it output a float with only one decimal place instead of two as per dictionary created.

The dictionary gave each item a price e.g "Taco": 3.00; surprisingly when I run debug dictionary has different value e.g "Taco": 3.0 instead of 3.00

I would like to know why it is behaving this way.

here is my code:

# make a dictionary
dict = {
    "Baja Taco": 4.00,
    "Burrito": 7.50,
    "Bowl": 8.50,
    "Nachos": 11.00,
    "Quesadilla": 8.50,
    "Super Burrito": 8.50,
    "Super Quesadilla": 9.50,
    "Taco": 3.00,
    "Tortilla Salad": 8.00
}
# with a while loop prompt for item and add item value until user input exit
total = 0
while True:
    try:
        item = input("Item: ").strip().title()
        for order in dict:
            if order == item:
                total = total + (dict[order])
                print(f"${total}")
    except EOFError:
        break

I expected my program to output a total of two decimal places instead of just one.

Answer 1

use print(f'Total: ${total:.2f}')

test it on python terminal:

x = 12.3
>>> print(f'{x:.2f}')
12.30
>>> print(f'{x:.3f}')
12.300
>>> print(f'{x:.4f}')
12.3000
>>> print(f'{x:.5f}')
12.30000
