Python Projects - Contact Management System in Python
This project is beginner-friendly and will help you understand basic Python concepts like lists, dictionaries, functions, loops, and file handling.
Python Projects for Beginners
A Contact Management System is a very good practical tool for organizing and managing contact information. It makes easy the process of storing and retrieving details, making it uses both personal and professional use. The Python project we built uses a simple functional for example of such a system, perfect for beginners to understand the core concepts.
- Contact Management System using Python. This system will allow users to:
- Add new contacts.
- View all contacts.
- Search for a contact by name.
- Update a contact's details.
- Delete a contact.
- Exit
Step 1: Set Up the Project
Install Python: Confirm that Python is installed on your system. or You can download it from this website python.org.
Choose an IDE:
Choose any IDE like PyCharm, VS Code, or even a simple text editor like Notepad.
Create a new Python file: Save it as contact_management.py.
Step 2: Define the Data Structure
Make a list of dictionaries to store contacts. Each contact will be represented as a dictionary with keys like name, phone, and email.
Python Code
# Initialize an empty list to store contacts
contacts = []
Now, we will create a menu to allow users to interact with the system.
Python Code
def display_menu():
print("\nContact Management System")
print("1. Add Contact")
print("2. View Contacts")
print("3. Search Contact")
print("4. Update Contact")
print("5. Delete Contact")
print("6. Exit")
This add contact function will allow users to add a new contact.
Python Code
def add_contact():
print("\nAdd New Contact")
name = input("Enter name: ")
phone = input("Enter phone number: ")
email = input("Enter email: ")
# Create a dictionary for the new contact
contact = {
"name": name,
"phone": phone,
"email": email
}
# Add the contact to the list
contacts.append(contact)
print(f"Contact '{name}' added successfully!")
View Contacts Function will display all the contacts stored in the list.
Python Code
def view_contacts():
print("\nAll Contacts")
if not contacts:
print("No contacts found.")
else:
for index, contact in enumerate(contacts, start=1):
print(f"{index}. Name: {contact['name']}, Phone: {contact['phone']}, Email: {contact['email']}")
Search Contact Function will allow users to search for a contact by name.
Python Code
def search_contact():
print("\nSearch Contact")
search_name = input("Enter name to search: ")
found_contacts = [contact for contact in contacts if search_name.lower() in contact['name'].lower()]
if found_contacts:
print("Matching Contacts:")
for contact in found_contacts:
print(f"Name: {contact['name']}, Phone: {contact['phone']}, Email: {contact['email']}")
else:
print("No matching contacts found.")
Update Contact Function will allow users to update a contact's details.
Python Code
def update_contact():
print("\nUpdate Contact")
name_to_update = input("Enter the name of the contact to update: ")
for contact in contacts:
if contact['name'].lower() == name_to_update.lower():
print(f"Current Details: Name: {contact['name']}, Phone: {contact['phone']}, Email: {contact['email']}")
contact['name'] = input("Enter new name (leave blank to keep current): ") or contact['name']
contact['phone'] = input("Enter new phone number (leave blank to keep current): ") or contact['phone']
contact['email'] = input("Enter new email (leave blank to keep current): ") or contact['email']
print("Contact updated successfully!")
return
print("Contact not found.")
Delete Contact Function will allow users to delete a contact.
Python Code
def delete_contact():
print("\nDelete Contact")
name_to_delete = input("Enter the name of the contact to delete: ")
for contact in contacts:
if contact['name'].lower() == name_to_delete.lower():
contacts.remove(contact)
print(f"Contact '{name_to_delete}' deleted successfully!")
return
print("Contact not found.")
Main Program Loop will keep the program running until the user chooses to exit.
Python Code
def main():
while True:
display_menu()
choice = input("Enter your choice (1-6): ")
if choice == '1':
add_contact()
elif choice == '2':
view_contacts()
elif choice == '3':
search_contact()
elif choice == '4':
update_contact()
elif choice == '5':
delete_contact()
elif choice == '6':
print("Exiting the Contact Management System. Goodbye!")
break
else:
print("Invalid choice. Please try again.")
Add the following code at the end of your file to start the program

if __name__ == "__main__":
main()
