Three likely possibilities, and one unlikely one:

(1) When you are running from a file, you are accidentally using the wrong
Python interpreter and trying to use Python 2 by mistake.

(2) When you are running from a file, you have invisible control characters
in the file, or the encoding is not set correctly, and are getting a
SyntaxError due to the control characters, nothing to do with annotations.

(3) There is some other syntax error in your file.

And the unlikely one:

(4) There's a bug in the interpreter.


If you would care to inspect the syntax error, you will see that when Python
finds a syntax error, it points at the offending token, or just after it,
using a ^ caret. That may give you some hint as to what the issue is.
