creating an 'adress book' in python using dictionaries?

[Larz60+]

dictionaries contain indexes by default

my_dict = {
    "Don": {
        "name": "Donald Jones", 
        "address": "1 Rue Rivoli Paris ", 
        "phone": "9444444411"
    }, 
    "Joseph": {
        "name": "Joseph Boy", 
        "address": "3 Tivoli Paris", 
        "phone": "0800838383"
    },
    "Bilbo": {
        "name": "Bilbo Baggin",
        "address": "4 White House Washington",
        "phone": "08055550838383"
    }
}

def fetch_details(name):
    print(f'\nWhat we know about {name}')
    for key, value in my_dict[name].items():
        print(f'{key}: {value}')

fetch_details('Joseph')
fetch_details('Don')

output:

Output:

name: Joseph Boy
address: 3 Tivoli Paris
phone: 0800838383
