A Dictionary in a Dictionary Syntax

[PythonGainz]

I'm getting a syntax error for the following code that I copied form a text book:

Code:

users = {
    "aeinstein": {
        "first": "albert",
        "last": "einstein",
        "location": "princeton"
        },
    
    "mccurie": {
        "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()}")

Here is the line that Python (Spyder) doesnt't like:

full_name = f"{user_info["first"]} {user_info["last"]}"

You need to either use triple quotes or single quotes for the string (or the keys). Otherwise Python will try to end the string at the second double quote it finds, so the line would ne syntactically invalid.

If I only change the keys the single quotes( 'aeinstein' and 'mccurie') I'm still getting an error message in the full_name line though, or do I need to change in other parts of the code?

Problem is that you have strings within a string. Python can't tell where one begins and the other one ends. you have three ways to fix this.
1. change the outer string from double quotes to single quotes.

    full_name = f'{user_info["first"]} {user_info["last"]}'

2. change the inner strings to use single quotes

    full_name = f"{user_info['first']} {user_info['last']}"

3. use the format() method

    full_name = "{} {}".format(user_info["first"],user_info["last"])
