Creating a restaurant/pizza menu in python, with a good layout

Question

I am new to python and would like to create a Pizza ordering system using python, that looks something like this.

1   Hawaiian                      $7.50
2   Champagne Ham & Cheese        $7.50
3   Beef & Onion                  $7.50
4   Pepperoni                     $7.50
5   Simply Cheese                 $7.50
6   Bacon & Mushroom              $7.50
7   Italiano                      $7.50
8   The Deluxe                    $13.50  
9   Ham, Egg & Hollandaise        $13.50
10  Americano                     $13.50
11  Mr Wedge                      $13.50
12  BBQ Meatlovers                $13.50

I would then like the customer to be able to select different pizzas based on the number so that they don't have to type Hawaiian, they can instead type 1. I have tried both dictionaries and lists but always resulted in this problem:

1  Hawaiian $7.50
2  Champagne Ham & Cheese$7.50
3  Beef & Onion $7.50
4  Pepperoni $7.50
5  Simply Cheese $7.50
6  Bacon & Mushroom $7.50
7  Italiano $7.50
8  The Deluxe $13.50 
9  Ham, Egg & Hollandaise $13.50
10  Americano $13.50
11  Mr Wedge $13.50 
12  BBQ Meatlovers $13.50

Where the prices would "stick to the pizza name" and the names of pizzas 10 onwards were indented by one character. Manually putting spaces does not seem like the most efficient way of going about my problem. e.g

standardprice = "$7.50"
    deluxeprice = "13.50"
    print (
    """   
1   Hawaiian                      %s
2   Champagne Ham & Cheese        %s
3   Beef & Onion                  %s
4   Pepperoni                     %s
5   Simply Cheese                 %s
6   Bacon & Mushroom              %s
7   Italiano                      %s
8   The Deluxe                    %s  
9   Ham, Egg & Hollandaise        %s
10  Americano                     %s
11  Mr Wedge                      %s
12  BBQ Meatlovers                %s
     """  % (standardprice, standardprice, standardprice, standardprice, 
             standardprice, standardprice, standardprice,deluxeprice,            
             deluxeprice,deluxeprice, deluxeprice, deluxeprice)
        )

Is there an easier way to solve my problem? Also as a side question when printing is there a way that "standardprice" variable applies to the first 7 elements and deluxe price applies to 8-12, rather than the crude way I have done it.

here had a somewhat similar problem but the page did not help.Code Academies "A day at the supermarket tutorial" was not particularly helpful either. I'm very new to python, so explaining like I know nothing would be very helpful

Answer 1

There are some super handy utilities for string formatting: ljust|rjust, for just this sort of thing.

Here's a quick example I whipped up using ljust, but don't stop here; take a peek at the doc linked above and let your imagination go wild with string-formatting-freedom!

from collections import namedtuple

MenuEntry = namedtuple('MenuEntry', ['index','description','price'])
_menu = []
_menu.append(MenuEntry(1, 'Hawaiian', '$7.50'))
_menu.append(MenuEntry(2, 'Champagne Ham & Cheese', '$7.50'))
_menu.append(MenuEntry(3, 'Beef & Onion', '$7.50'))
_menu.append(MenuEntry(40, 'Pepperoni', '$10.50'))
_menu.append(MenuEntry(100, 'Simply Cheese', '$17.50'))

for entry in _menu:
    index = str(getattr(entry,'index')).ljust(5)
    descr = getattr(entry,'description').ljust(25)
    price = getattr(entry,'price').ljust(7)
    print '{0}{1}{2}'.format(index,descr,price)

""" Output: """

1    Hawaiian                 $7.50  
2    Champagne Ham & Cheese   $7.50  
3    Beef & Onion             $7.50  
40   Pepperoni                $10.50 
100  Simply Cheese            $17.50

Here's a working example, but I used the pandas library to save myself lots of grief. Go through the comments first if you can/want, then hit back if you have other questions.

Admittedly, this is not for beginners, but except for the formatting part for the DataFrame, it's pretty basic.

import pandas as pd

pizzas = [
    "Hawaiian",
    "Champagne Ham & Cheese",
    "Beef & Onion",
    "Pepperoni",
    "Simply Cheese",
    "Bacon & Mushroom",
    "Italiano",
    "The Deluxe",
    "Ham, Egg & Hollandaise",
    "Americano",
    "Mr Wedge",
    "BBQ Meatlovers"
    ]

df = pd.DataFrame(pizzas, columns=["Pizzas"])
df.loc[:8, "Prices"] = 7.50     # First 7 items.
df.loc[8:, "Prices"] = 13.50    # All the rest.
df.index += 1                   # So that it's not zero-indexed.
total_bill = 0.0                # Meh.

print "Welcome to Pizza Planet!" # So unoriginal, I know.
print
print "Here's our menu!"
print
# Following method taken and modified from unutbu's amazing answer
# here: http://stackoverflow.com/questions/25777037
print df.to_string(justify='left',
                   header=False,
                   formatters={
                    'Pizzas':'{{:<{}s}}'.format(
                        df['Pizzas'].str.len().max()
                        ).format,
                    'Prices':'     ${:.2f}'.format})
print
print "Input a number and press enter to select an item."
print "Input 'done' to finish your order and tabulate your bill."
print "Input 'exit' to cancel your orders."

while True:

    order = raw_input(">>>  ")

    if order == 'exit':
        break
    elif order == 'done':
        print "Your total bill is ${:.2f}.".format(total_bill)
        raw_input("Press any key to exit.")
        break
    elif int(order) in df.index:
        item = df.loc[int(order), "Pizzas"]     # Get the respective items
        price = df.loc[int(order), "Prices"]    # by indexing order input.
        print "You've selected {}! That would be ${:.2f}.".format(item, price)
        total_bill += price
        continue
    else:
        print "Don't be an idiot." # :-)
        raw_input("Press any key to exit.")
        break

Result:

menu = int(input("   ORDER PLEASE \n 1.kanji with \n 2. fish with \n 3.rise with chicken \n \n   Select Yours"))

if menu == 1:
    print("\n kanji with $10 ")

    conform =int(input("\n conform to press one"))

    if conform ==1:
        print("\n Order confirmed")
    else:
        print("chose correct option")

elif menu == 2:
    print("\n fwith booti $15")

    confm = int(input("\nconform to press one"))

    if confm == 1:
        print("\n Order confirmed")
    else:
        print("chose correct option")

elif menu == 3:
    print("\npoola with booti $20")

    conform = int(input("\n conform to press one"))

    if conform == 1:
        print("\n Order confirmed")
    else:
        print("chose correct option")

else:
    print("\n WRONG SELECTION")

Answer 4

Here's a quick and dirty version, you should of course do some checking to avoid errors. But this will work:

from collections import OrderedDict

thatsALowPrice = 7.50
thatsAHighPrice = 10.50

myMenu = OrderedDict()

myMenu["Sandwich"] = thatsALowPrice
myMenu["Burger"] = thatsALowPrice
myMenu["Steak"] = thatsAHighPrice

i=1
for k, v in myMenu.items():
    print(i, ":", k, "\t\t", v)
    i+=1

itemNumber = int(input("Choose your item: "))
item=list(myMenu.items())[itemNumber-1]

print("You chose", item[0], "at a price of: $"+str(item[1]))
