SyntaxError: EOF while scanning triple-quoted string literal

[Caroline]

You need to provide at the very least the stacktrace, and you should really provide enough code to reproduce the issue. As it stands, this would say admin is not defined. Ideally, you would provide the minimal instructions for reproducing the issue (likely ten or fewer lines of code here).

Do you mean that I need to add more codes before the second url statement to define admin? And if so, do you mind suggesting some ways for me to work this out?
