求解这个代码哪里有问题

users = {
    'aeinstein': {
        'first': 'albert',
        'last': 'einstein',
        'locating': 'princeton'
    },

    'mcurie': {
        'first': 'marie',
        'last': 'curie',
        'location': 'paris',
    },
}

for username, user_info in users.items():
    print(f"\nUsername:{username}")
    full_name = f"{user_info['first']} {user_info['last']}"
    location = user_info['location']

    print(f"\tFull name:{full_name.title()}")
    print(f"\tLocation:{location.title()}")

两个user，一个写的locating,一个写的location
