This Python contact book program saves user input as a contact book description and retrieves it as search results. It is a fundamental program that shows how simple logic works using arrays, loops, and conditional statements.
Example:
An example of a Contact book in Python:
names = []
contact_numbers = []
num = int(input("Enter the total number of contacts you want to save: "))
for i in range(num):
name = input("Name: ")
contact_number = int(input("Contact Number: "))
names.append(name)
contact_numbers.append(contact_number)
print("\nName\t\t\tContact Number\n")
for i in range(num):
print("{}\t\t\t{}".format(names[i], contact_numbers[i]))
search_term = input("\nEnter search term: ")
print("Search result:")
if search_term in names:
index = names.index(search_term)
contact_number = contact_numbers[index]
print("Name: {}, Phone Number: {}".format(search_term, contact_number))
else:
print("No records")Program Output:
Enter the total number of contacts you want to save: 2 Name: Alex Contact Number: 123456789 Name: Amara Contact Number: 984321 Name Contact Number Alex 123456789 Amara 987654321 Enter search term: Alex Search result: Name: Alex, Phone Number: 123456789
