Per the spec hints:

If str is an INSERT, and the table into which data was inserted contains an autoincrementing PRIMARY KEY, then execute returns the value of the newly inserted row’s primary key.

So your result is not a dictionary, it's an integer (the value of the primary key). You can simply store result directly.

  • ok so are you saying that i cant use the nt operator since it only operates on objects and since result is an int i should use this:if result > 0 : return apology("username already taken", 403). – user21692 Jul 11 '18 at 3:10
  • No, I was saying that you can't access result[0]["id"] when setting the session id. – curiouskiwi Jul 12 '18 at 3:24
