如何获取给定列表中的联系人

# 定义联系人列表
contacts = [
    {"姓名": "张三", "电话": "123456789", "邮箱": "zhangsan@example.com"},
    {"姓名": "李四", "电话": "987654321", "邮箱": "lisi@example.com"},
    {"姓名": "王五", "电话": "456789123", "邮箱": "wangwu@example.com"}
]

# 给定的姓名
given_name = "李四"

# 遍历联系人列表，查找匹配的联系人
matched_contacts = []
for contact in contacts:
    if contact["姓名"] == given_name:
        matched_contacts.append(contact)

# 输出匹配的联系人信息
if len(matched_contacts) > 0:
    for contact in matched_contacts:
        print("姓名:", contact["姓名"])
        print("电话:", contact["电话"])
        print("邮箱:", contact["邮箱"])
else:
    print("未找到该联系人。")
