7.16 LAB: Breakout room activity - Interactive Menu

Learning Goals

use a dictionary to store menu items
use a function to print formatted menu options
use a while loop to create an interactive program
check the user input using if branches
check that an option is correct (verify that a dictionary key exists)
use break to interrupt the program execution

Introduction

In this lab, we will be building an application that uses an interactive menu.

Let's say our high-level menu has the following options:

L : List A : Add E : Edit D : Delete M: Show statistical data S : Save the data R : Restore data from file Q : Quit this program

These key-option mappings will be stored in a dictionary in the main program.

print_main_menu() function

Write the print_main_menu() that accepts a dictionary of keys-options like the one shown above and prints the menu options stored in that dictionary in an easy-to-read format. Below is an example of the result of calling print_main_menu() (notice the question it asks at the top - it is part of the function output):

Example

Given the menu with the following options as mentioned above, the call to print_main_menu(main_menu) will output:

========================== What would you like to do? L - List A - Add E - Edit D - Delete M - Show statistical data S - Save the data R - Restore data from file Q - Quit this program ==========================

Program flow

The expected program flow is:

The main program starts with a menu of options given above
Loop indefinitely (while the user didn't choose to exit):
- Print the menu to the user
- Get the user's choice from input()
- Check if the user's choice is a valid option in the menu (is it one of the dictionary keys?).
  - If the input is a valid option, print the option that user selected
  - If not, simply continue from the top of the loop
- If the user entered 'Q', break the while loop

Instructions

Fix TODO 1: Add the options from the instructions to the_menu dictionary inside the main program.
Fix TODO 2: Implement the "Quit" option, breaking from the while loop if the user input is an uppercase OR lowercase "Q".
Fix TODO 3: Check whether a provided option is a valid menu option.

Each time a valid menu option is provided, the program "echoes" it back to the user as follows:

print(f"You selected option {opt} to > {the_menu[opt]}.")

Please Use PYTHON

def print_main_menu(menu):
"""
Given a dictionary with the menu,
prints the keys and values as the
formatted options.
Adds additional prints for decoration
and outputs a question
"What would you like to do?"
"""

if __name__ == "__main__":
the_menu = {} # TODO 1: add the options from the instructions
opt = None

while True:
# print_main_menu(...) # TODO 1: uncomment, define the function, and call with the menu as an argument
print("::: Enter an option")
opt = input("> ")

if opt == ...: # TODO 2: make Q or q quit the program
print("Goodbye!\n")
break # exit the main `while` loop
else:
if ...: # TODO 3: check of the character stored in opt is in the_menu dictionary
print(f"You selected option {opt} to > {the_menu[opt]}.")
else:
print(f"WARNING: {opt} is an invalid option.\n")

**Lab Activity: Breakout Room Activity - Interactive Menu (7.16.1)**

**File: main.py**

The image shows the beginning of a Python script that defines a function called `print_main_menu`. Below is a transcription of the code and comments present:

```python
def print_main_menu(menu):
"""
Given a dictionary with the menu,
prints the keys and values as the
formatted options.
Adds additional prints for decoration
and outputs a question
"What would you like to do?"
"""
```

**Explanation of Code:**

- **Function Definition:** The function `print_main_menu` takes one parameter, `menu`, which is expected to be a dictionary.
- **Docstring:**
- The function is designed to:
- Print the keys and values of the `menu` dictionary in a formatted manner as menu options.
- Add decorative prints to enhance the appearance.
- Prompt the user with the question: "What would you like to do?"

**Contextual Notes:**

- This script is part of a lab activity focusing on creating interactive menus using Python.
- Students are likely expected to complete the function implementation and ensure it works with a provided or custom dictionary.

The screenshot also includes navigation elements such as a "Lab Activity" breadcrumb and an indication of progress (0/13), but no graphs or additional diagrams are shown.

The provided script is a Python program designed for a command-line menu interface. The script will likely appear on an educational website to demonstrate basic control flow and input handling in Python. Below is a transcription and explanation of the code:

```python
if __name__ == "__main__":
the_menu = {} # TODO 1: add the options from the instructions
opt = None

while True:
# print_main_menu(...) # TODO 1: uncomment, define the function, and call with the menu as an argument
print("::: Enter an option")
opt = input("> ")

if opt == ...: # TODO 2: make Q or q quit the program
print("Goodbye!\n")
break # exit the main `while` loop
else:
if ...: # TODO 3: check if the character stored in opt is in `the_menu` dictionary
print(f"You selected option {opt} to > {the_menu[opt]}.")
else:
print(f"WARNING: {opt} is an invalid option.\n")
```

### Detailed Explanation:

1. **Initialization**:
- `the_menu` is a dictionary intended to hold menu options. It’s currently empty and requires filling as per instructions.
- `opt` is initialized as `None` to store user input.

2. **Main Loop**:
- A `while True` loop continuously runs, allowing users to interact with the menu until a specific condition is met to exit.

3. **User Input**:
- The program prompts the user to enter an option with `print("::: Enter an option")` followed by `input("> ")` to capture input.

4. **Condition for Quitting**:
- A placeholder condition `if opt == ...:` is set up for quitting the program. The developer should replace `...` with conditions like if `opt` is 'Q' or 'q'.

5. **Menu Selection**:
- The code checks if the input `opt` exists in `the_menu` dictionary.
- If `opt` is valid, it prints the associated menu item.
- If not, it warns the user that the option is invalid.

### To Do:
- **TODO 1**: Add options to `the_menu` and define the `print_main_menu()` function.
- **TODO 2**: Implement
