cs50 pset7 houses syntax

I’m working on the roster.py part of the problem and I’m getting the error:

   File "roster.py", line 17
    print(f"{row["first"]} {row["middle"]} {row["last"]}, born {row["birth"]}")
                      ^
SyntaxError: invalid syntax

My code:

import sys
from cs50 import SQL

if len(sys.argv) != 2:
    print("Needs two command-line argument")
    exit(1)

db = SQL("sqlite:///students.db")

house = sys.argv[1]

results = db.execute("SELECT * FROM students WHERE house = ?", house)


for row in results:
    if row["middle"] != None:
        print(f"{row["first"]} {row["middle"]} {row["last"]}, born {row["birth"]}")
    else:
        print(f"{row["first"]} {row["last"]}, born {row["birth"]}")

Answer

Your quotes are wrong. Try this:

for row in results:
    if row["middle"] != None:
        print(f'{row["first"]} {row["middle"]} {row["last"]}, born {row["birth"]}')
    else:
        print(f'{row["first"]} {row["last"]}, born {row["birth"]}')
