Python - 28: Building a Contact Manager

Let's combine lists, dictionaries, loops, and functions to build a simple contact manager.

Your challenge: Add contacts to a list, display them, and search for one contact by name.

Store contacts as dictionaries

Each contact can be a dictionary with keys such as "name" and "phone".

Keep contacts in a list

The add_contact() function creates a dictionary and adds it to the contacts list with append().

Display the contacts

Loop through the list and access each value with its key: contact["name"]

Search by name

Loop through the contacts again and compare each name with search_name.

Try it: Change search_name and add another fictional contact to the list.

Good Python habit: Use a dictionary when several related values belong to one item, then use a list when you need to store many of those items.

contacts = []

def add_contact(name, phone):

    contact = {
        "name": name,
        "phone": phone
    }

    contacts.append(contact)

add_contact("Alex", "555-1234")
add_contact("Sam", "555-9876")
add_contact("Taylor", "555-5555")

print("Contact List:")

for contact in contacts:

    print("Name:")
    print(contact["name"])

    print("Phone:")
    print(contact["phone"])

    print("---")

search_name = "Sam"

print("Searching for:")
print(search_name)

for contact in contacts:

    if contact["name"] == search_name:

        print("Contact Found!")
        print(contact["phone"])
