用Python语言生成一个手机通讯录管理系统，其功能包括查询信息，分组，修改

好的，下面是一个简单的 Python 通讯录管理系统代码示例：

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

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

    def add_contact(self, contact):
        self.contacts.append(contact)

    def remove_contact(self, contact):
        self.contacts.remove(contact)

    def search_contact(self, name):
        for contact in self.contacts:
            if contact.name == name:
                return contact

    def group_contacts(self):
        groups = {}
        for contact in self.contacts:
            if contact.email not in groups:
                groups[contact.email] = []
            groups[contact.email].append(contact)
        return groups

    def update_contact(self, contact, name, phone, email):
        contact.name = name
        contact.phone = phone
        contact.email = email

def main():
    contacts = ContactBook()

    while True:
        print("1. Add Contact")
        print("2. Remove Contact")
        print("3. Search Contact")
        print("4. Group Contacts")
        print("5. Update Contact")
        print("6. Exit")

        choice = input("Enter your choice: ")

        if choice == "1":
            name = input("Enter name: ")
            phone = input("Enter phone: ")
            email = input("Enter email: ")
            contact = Contact(name, phone, email)
            contacts.add_contact(contact)
            print("Contact added successfully.")

        elif choice == "2":
            name = input("Enter name: ")
            contact = contacts.search_contact(name)
            if contact:
                contacts.remove_contact(contact)
                print("Contact removed successfully.")
            else:
                print("Contact not found.")

        elif choice == "3":
            name = input("Enter name: ")
            contact = contacts.search_contact(name)
            if contact:
                print("Name:", contact.name)
                print("Phone:", contact.phone)
                print("Email:", contact.email)
            else:
                print("Contact not found.")

        elif choice == "4":
            groups = contacts.group_contacts()
            for email, group in groups.items():
                print("Email:", email)
                for contact in group:
                    print("Name:", contact.name)
                    print("Phone:", contact.phone)
                print()

        elif choice == "5":
            name = input("Enter name: ")
            contact = contacts.search_contact(name)
            if contact:
                new_name = input("Enter new name: ")
                new_phone = input("Enter new phone: ")
                new_email = input("Enter new email: ")
                contacts.update_contact(contact, new_name, new_phone, new_email)
                print("Contact updated successfully.")
            else:
                print("Contact not found.")

        elif choice == "6":
            break

        else:
            print("Invalid choice.")

if __name__ == "__main__":
    main()

这个程序中定义了两个类：`Contact` 和 `ContactBook`。`Contact` 类表示一个联系人，包括姓名、电话和电子邮件。`ContactBook` 类表示整个通讯录，包括一组联系人，以及添加、删除、查询、分组和修改联系人的方法。

在主函数中，使用一个循环显示菜单，根据用户的选择执行相应的操作。用户可以添加、删除、查询、分组和修改联系人，也可以退出程序。
