下面是一个简单的Python通讯录程序代码示例:
class Contact:
def __init__(self, name, phone_number):
self.name = name
self.phone_number = phone_number
class AddressBook:
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
return None
def display_contacts(self):
if len(self.contacts) == 0:
print("No contacts found.")
else:
for contact in self.contacts:
print(f"Name: {contact.name}, Phone Number: {contact.phone_number}")
def main():
address_book = AddressBook()
while True:
print("1. Add Contact")
print("2. Remove Contact")
print("3. Search Contact")
print("4. Display All Contacts")
print("5. Quit")
choice = input("Enter your choice: ")
if choice == "1":
name = input("Enter name: ")
phone_number = input("Enter phone number: ")
contact = Contact(name, phone_number)
address_book.add_contact(contact)
print("Contact added.")
elif choice == "2":
name = input("Enter name: ")
contact = address_book.search_contact(name)
if contact:
address_book.remove_contact(contact)
print("Contact removed.")
else:
print("Contact not found.")
elif choice == "3":
name = input("Enter name: ")
contact = address_book.search_contact(name)
if contact:
print(f"Name: {contact.name}, Phone Number: {contact.phone_number}")
else:
print("Contact not found.")
elif choice == "4":
address_book.display_contacts()
elif choice == "5":
break
else:
print("Invalid choice. Please try again.")
if __name__ == "__main__":
main()
这个程序通过创建Contact
类和AddressBook
类来实现通讯录的功能。Contact
类用于表示一个联系人,包含姓名和电话号码两个属性。AddressBook
类用于表示通讯录,包含一个联系人列表,以及添加、删除、搜索和显示联系人的方法。
在main
函数中,通过一个无限循环,根据用户的选择执行相应的操作,包括添加联系人、删除联系人、搜索联系人、显示所有联系人以及退出程序。
注意:上述代码只是一个简单的示例,实际的通讯录程序可能需要更多的功能和优化。
