Python Contact Detailed Explanation

1. Introduction

Python’s Contact module provides a simple and efficient way to work with contact information, including creating, editing, deleting, and searching for contacts. This article will introduce the Contact module in detail and demonstrate its functionality and results through sample code.

2. Installation

The Contact module is part of the Python standard library, so you don’t need to install it separately. Simply ensure that it’s installed for your version of Python.

3. Module Import

Before using the Contact module, you need to import it. You can use the following code to import the Contact module:

import Contact

4. Creating Contacts

The Contact module makes it easy to create new contacts. First, we use the new_contact() method to create a new contact object. We can then set properties for the contact object, such as name, phone number, and email address. Finally, we use the save() method to save the contact information. The following is a sample code:

import Contact

contact = Contact.new_contact()
contact.name = "张三"
contact.phone = "123456789"
contact.email = "zhangsan@example.com"

contact.save()

After running the above code, the contact information will be saved in the system.

5. Editing Contact Information

If you need to modify the information of an existing contact, you can use the edit_contact() method of the Contact module. This method first accepts the contact’s unique identifier as a parameter and then retrieves the contact’s detailed information. Next, you can modify the contact’s properties as needed and save the changes using the save() method. The following is a sample code:

import Contact

contact_id = 1 # Assume the contact's unique identifier is 1

contact = Contact.edit_contact(contact_id)
contact.name = "Li Si"
contact.phone = "987654321"

contact.save()

After running the above code, the contact’s name and phone number will be updated.

6. Deleting Contacts

In some cases, you may need to delete a contact from your contact list. The Contact module provides the delete_contact() method to accomplish this. This method accepts a contact’s unique identifier as a parameter and deletes the corresponding contact information from the system. The following is a sample code:

import Contact

contact_id = 1 # Assume the contact’s unique identifier is 1

Contact.delete_contact(contact_id)

After running the above code, the contact will be permanently deleted.

7. Searching Contacts

The Contact module also supports searching for contacts based on various criteria. You can use the search_contact() method to do this. This method accepts a dictionary containing the criteria to search for and their corresponding values. The following is a sample code:

import Contact

search_criteria = {
"name": "张三",
"phone": "123456789"
}

results = Contact.search_contact(search_criteria)

for contact in results:
print(contact.name, contact.phone, contact.email)

Running the above code will print the name, phone number, and email address of the contacts that meet the search criteria.

Conclusion

The Contact module provides simple yet powerful tools for working with contact information. By creating, editing, deleting, and searching for contacts, we can effectively manage our contact list.
