更有效地为列表的子列表分配名称

# 原始数据
users = [
    ["Alice", 30, "alice@example.com"],
    ["Bob", 25, "bob@example.com"],
    ["Charlie", 35, "charlie@example.com"]
]

# 为子列表分配名称
user_names = [user[0] for user in users]
user_ages = [user[1] for user in users]
user_emails = [user[2] for user in users]

print("User Names:", user_names)
print("User Ages:", user_ages)
print("User Emails:", user_emails)

# 使用字典来存储用户信息
users_dict = {
    "Alice": {"age": 30, "email": "alice@example.com"},
    "Bob": {"age": 25, "email": "bob@example.com"},
    "Charlie": {"age": 35, "email": "charlie@example.com"}
}

print("User Names:", list(users_dict.keys()))
print("User Ages:", [user["age"] for user in users_dict.values()])
print("User Emails:", [user["email"] for user in users_dict.values()])
