用python写一个电话管理系统，包括1，添加联系人，2，删除联系人，3，搜索联系人4，编辑联系人，5，显示联系人

好的，以下是一个包含添加、删除、搜索、编辑和显示联系人的电话管理系统Python代码：

class Contact:
    def __init__(self, name, phone_number, email):
        self.name = name
        self.phone_number = phone_number
        self.email = email

class Phonebook:
    def __init__(self):
        self.contacts = []

    def add_contact(self, name, phone_number, email):
        contact = Contact(name, phone_number, email)
        self.contacts.append(contact)
        print("Contact added.")

    def search_contact(self, name):
        for contact in self.contacts:
            if contact.name == name:
                print(f"Name: {contact.name} Phone number: {contact.phone_number} Email: {contact.email}")
                return
        print("Contact not found.")

    def remove_contact(self, name):
        for contact in self.contacts:
            if contact.name == name:
                self.contacts.remove(contact)
                print("Contact removed.")
                return
        print("Contact not found.")

    def edit_contact(self, name):
        for contact in self.contacts:
            if contact.name == name:
                new_name = input("Enter the new name (press enter to skip): ")
                new_phone_number = input("Enter the new phone number (press enter to skip): ")
                new_email = input("Enter the new email (press enter to skip): ")
                if new_name:
                    contact.name = new_name
                if new_phone_number:
                    contact.phone_number = new_phone_number
                if new_email:
                    contact.email = new_email
                print("Contact edited.")
                return
        print("Contact not found.")

    def display_contacts(self):
        if self.contacts:
            for contact in self.contacts:
                print(f"Name: {contact.name} Phone number: {contact.phone_number} Email: {contact.email}")
        else:
            print("No contacts found.")

phonebook = Phonebook()

while True:
    print("1. Add contact")
    print("2. Search contact")
    print("3. Remove contact")
    print("4. Edit contact")
    print("5. Display contacts")
    print("6. Quit")

    choice = input("Enter your choice: ")

    if choice == "1":
        name = input("Enter the name: ")
        phone_number = input("Enter the phone number: ")
        email = input("Enter the email: ")
        phonebook.add_contact(name, phone_number, email)

    elif choice == "2":
        name = input("Enter the name: ")
        phonebook.search_contact(name)

    elif choice == "3":
        name = input("Enter the name: ")
        phonebook.remove_contact(name)

    elif choice == "4":
        name = input("Enter the name: ")
        phonebook.edit_contact(name)

    elif choice == "5":
        phonebook.display_contacts()

    elif choice == "6":
        break

    else:
        print("Invalid choice. Please try again.")

这个电话管理系统使用了Python类和对象的概念，包括联系人（Contact）和电话簿（Phonebook）两个类。您可以通过选择不同的选项来添加、删除、搜索、编辑和显示联系人。
