using Python. Practice 9-2 continue to practice 9-1 and I will write the birthday dictionary because I couldn't take a pic of it

birthday dictionary code

# This program uses a dictionary to keep friends'
# names and birthdays.

# Global constants for menu choices
LOOK_UP = 1
ADD = 2
CHANGE = 3
DELETE = 4
QUIT = 5

# main function
def main():
    # Create an empty dictionary.
    birthdays = {}

    # Initialize a variable for the user's choice.
    choice = 0

    while choice != QUIT:
        # Get the user's menu choice.
        choice = get_menu_choice()

        # Process the choice.
        if choice == LOOK_UP:
            look_up(birthdays)
        elif choice == ADD:
            add(birthdays)
        elif choice == CHANGE:
            change(birthdays)
        elif choice == DELETE:
            delete(birthdays)

# The get_menu_choice function displays the menu
# and gets a validated choice from the user.
def get_menu_choice():
    print()
    print('Friends and Their Birthdays')
    print('---------------------------')
    print('1. Look up a birthday')
    print('2. Add a new birthday')
    print('3. Change a birthday')
    print('4. Delete a birthday')
    print('5. Quit the program')
    print()

    # Get the user's choice.
    choice = int(input('Enter your choice: '))

    # Validate the choice.
    while choice < LOOK_UP or choice > QUIT:
        choice = int(input('Enter a valid choice: '))

    # return the user's choice.
    return choice

# The look_up function looks up a name in the
# birthdays dictionary.
def look_up(birthdays):
    # Get a name to look up.
    name = input('Enter a name: ')

    # Look it up in the dictionary.
    print(birthdays.get(name, 'Not found.'))

# The add function adds a new entry into the
# birthdays dictionary.
def add(birthdays):
    # Get a name and birthday.
    name = input('Enter a name: ')
    bday = input('Enter a birthday: ')

    # If the name does not exist, add it.
    if name not in birthdays:
        birthdays[name] = bday
    else:
        print('That entry already exists.')

# The change function changes an existing
# entry in the birthdays dictionary.
def change(birthdays):
    # Get a name to look up.
    name = input('Enter a name: ')

    if name in birthdays:
        # Get a new birthday.
        bday = input('Enter the new birthday: ')

        # Update the entry.
        birthdays[name] = bday
    else:
        print('That name is not found.')

# The delete function deletes an entry from the
# birthdays dictionary.
def delete(birthdays):
    # Get a name to look up.
    name = input('Enter a name: ')

    # If the name is found, delete the entry.
    if name in birthdays:
        del birthdays[name]
    else:
        print('That name is not found.')

# Call the main function.
main()

    

**Practice Assignment Ch. 9-2**

Still in the groups from last class (online students do remainder of assignment), using the dictionary application you created, add two new menu items:

- Save the dictionary — write a function to pickle the dictionary to a file
- Retrieve the dictionary — write a function to retrieve the pickled dictionary that was saved earlier
- Put both functions in a separate module that is imported by your main program

Turn in your programs/modules to the practice assignment link in course content.

**Practice Assignment Ch. 9-1**

1. **Classroom Sections:** Group assignment – break into groups of 3 or 4.

2. **Online students:** Do on your own.

3. Using the example of the birthday dictionary in Chapter 9, create a dictionary application, subject of your choosing (appropriate content).

4. In addition to the menu choices provided to the user in the example, add menu items to display the entire dictionary.

5. Each person will create a separate module for their function(s) with the main program importing all the modules.
   - **Person 1** – Main program/menu display, coordinates other programs
   - **Person 2** – Look up and display functions
   - **Person 3** – Add function
   - **Person 4** – Change, and Delete functions

Turn in your programs/modules to the practice assignment link in course content.
