我的字典功能有问题。

den = {
    'first_name': 'den',
    'last_name': 'elc',
    'age': '16',
    'city': 'slovakia',
}
for user, user_info in den.items():
    nameo = user_info['first_name']
    namei = user_info['last_name']
    age = user_info['age']
    city = user_info['city']
    print(f"\tFirst name:{nameo}")
    print(f"\tLast_name:{namei}")
    print(f"\tAge:{age}")
    print(f"\tCity:{city}")

Python 打印此 TypeError：

    Traceback (most recent call last):
  File "D:/PyCharm Community/pycharm/venv/Test.py", line 15, in <module>
    nameo = user_info['first_name']
TypeError: string indices must be integers

有任何想法吗？
