Felipe’s Taqueria

One of the most popular places to eat in Harvard Square is Felipe’s Taqueria, which offers a [menu[(https://www.felipesboston.com/menu)] of entrees, per the dict below, wherein the value of each key is a price in dollars:

	{
		"Baja Taco": 4.25,
		"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
	}

In a file called taqueria.py, implement a program that enables a user to place an order, prompting them for items, one per line, until the user inputs control-d (which is a common way of ending one’s input to a program). After each inputted item, display the total cost of all items inputted thus far, prefixed with a dollar sign ($) and formatted to two decimal places. Treat the user’s input case insensitively. Ignore any input that isn’t an item. Assume that every item on the menu will be titlecased.

Hints

• Note that you can detect when the user has inputted control-d by catching an [EOFError](https://docs.python.org/3/library/exceptions.html#EOFError) with code like:

    try:
    	item = input()
    except EOFError:
    	...

You might want to print a new line so that the user’s cursor (and subsequent prompt) doesn’t remain on the same line as your program’s own prompt.

• Inputting control-d does not require inputting Enter as well, and so the user’s cursor (and subsequent prompt) might thus remain on the same line as your program’s own prompt. You can move the user’s cursor to a new line by printing \n yourself!

• Note that a dict comes with quite a few methods, per docs.python.org/3/library/stdtypes.html#mapping-types-dict, among them get, and supports operations like:

    d[key]
    and
  
    if key in d:
    	...

wherein d is a dict and key is a str.

Be sure to avoid or catch any KeyError.

Before You Begin

From the root of your repository execute cd 3-Exceptions So your current working directory is ...

	/3-Exceptions $:

Next execute

	mkdir taqueria

to make a folder called taqueria in your codespace.

Then execute

	cd taqueria

to change directories into that folder. You should now see your terminal prompt as /3-Exceptions/taqueria $. You can now execute

	code taqueria.py

to make a file called taqueria.py where you’ll write your program.

How to Test

Here’s how to test your code manually:

1. Run your program with python taqueria.py. Type Taco and press Enter, then type Taco again and press Enter. Your program should output:

    Total: $6.00  

and continue prompting the user until they input control-d.

2. Run your program with python taqueria.py. Type Baja Taco and press Enter, then type Tortilla Salad and press enter. Your program should output:

    Total: $12.25

and continue prompting the user until they input control-d.

3. Run your program with python taqueria.py. Type Burger and press Enter. Your program should reprompt the user.

4. Be sure to try other foods and vary the casing of your input. Your program should behave as expected, case-insensitively.

Commit your program to GITHUB

At the /3-Exceptions/taqueria $ prompt in your terminal:

	git add -A 

Add all changed files in the repository to be committed

	git commit -m “Upload completed taqueria.py“

Commit all changes in the REPO with the comment “Upload completed taqueriataqueria.py“ note: If the file is not complete, adjust the comment to describes what is being commited
