Overview

How to use the project

Step 1: Setting up Initial Requirements:

1. Python 3.11 and above — Follow this link to download Python for your operating system. You can refer to these tutorials on YouTube for the same — Windows, Mac-OS, Ubuntu (it’ll be somewhat similar for other Linux distributions).

2. pip — pip has been included with the Python installer since versions 3.4 for Python 3 and 2.7.

3. Install pipenv using pip — pip install pipenv

Step 2: Setting up Python Virtual Environment using pipenv:

1. Install required dependencies using pipenv — pipenv install
2. Activate Python Virtual Environment — pipenv shell
3. Run the program — python main.py

Here is a code snippet:

menu = {
    1: {'name': 'espresso',
        'price': 1.99},
    2: {'name': 'coffee',
        'price': 2.50},
    3: {'name': 'cake',
        'price': 2.79},
    4: {'name': 'soup',
        'price': 4.50},
    5: {'name': 'sandwich',
        'price': 4.99}
}


# DISPLAY MENU
def display_menu():
    print('------- Menu -------')
    for selection in menu:
        # pads the output string of menu[selection]['name'] to a width of 9 characters, aligning it to the left of that space.
        # pads the output string of menu[selection]['price'] to a width of 5 characters, aligning it to the right of that space.
        print(
            f"{selection}. {menu[selection]['name'] : <9} | {menu[selection]['price'] : >5}")
    print()


# TAKE ORDER
def take_order():
    display_menu()
    order = []
    count = 1
    for i in range(3):
        item = input(f'Select menu item number {count} (from 1 to 5): ')
        count += 1
        order.append(menu[int(item)])
    return order


# PRINT ORDER
def print_order(order):
    print('\n')
    print('You have ordered ' + str(len(order)) + ' items')
    items = []
    items = [item['name'] for item in order]
    print(items)
    return order
