Contact Book (Python Project)


Create a contact book application to store, view, and manage contacts.

 

 

 

 

Key Concepts:

  • File handling (CSV or JSON)
  • Lists and dictionaries
  • User input

 

Starting Point:

import csv
def add_contact(contacts):
   name = input("Enter name: ")
   phone = input("Enter phone number: ")
   contacts.append({'name': name, 'phone': phone})
def view_contacts(contacts):
   print("Contacts:")
   for contact in contacts:
       print(f"Name: {contact['name']}, Phone: {contact['phone']}")
def load_contacts(filename):
   try:
       with open(filename, mode='r') as file:
           reader = csv.DictReader(file)
           return list(reader)
   except FileNotFoundError:
       return []
def save_contacts(filename, contacts):
   with open(filename, mode='w', newline='') as file:
       writer = csv.DictWriter(file, fieldnames=['name', 'phone'])
       writer.writeheader()
       writer.writerows(contacts)
def main():
   contacts = load_contacts('contacts.csv')
   while True:
       print("\n1. Add Contact\n2. View Contacts\n3. Save and Exit")
       choice = input("Enter your choice: ")
       
       if choice == '1':
           add_contact(contacts)
       elif choice == '2':
           view_contacts(contacts)
       elif choice == '3':
           save_contacts('contacts.csv', contacts)
           break
       else:
           print("Invalid choice!")
if __name__ == "__main__":
   main()
 

These projects can help you practice and reinforce your understanding of Python programming concepts. As you build these projects, you can add more features and complexity to challenge yourself further.
