"Run Selection" does not handle decorators properly.

def my_decorator(func):
    def wrapper():
        print("Something is happening before the function is called.")
        func()
        print("Something is happening after the function is called.")
    return wrapper


@my_decorator
def say_whee():
    print("Whee!")


say_whee()

shift+enter or ‘run’ button in vscode

...     def wrapper():
...         print("Something is happening before the function is called.")

...         print("Something is happening after the function is called.")
...     return wrapper

Verification steps:

• Download the latest Insiders version of the Python extension
• Copy the code from the original message:

def my_decorator(func):
    def wrapper():
        print("Something is happening before the function is called.")
        func()
        print("Something is happening after the function is called.")
    return wrapper


@my_decorator
def say_whee():
    print("Whee!")


say_whee()

• Select it all and press shift + enter or run the Run Selection/Line in Terminal command
• Make sure that the code is passed to the terminal and executed without any errors

What appears to be happening is the following:

• the decorator gets executed as a single line in isolation, which produces a syntax error.
• the undecorated/plain python statement beneath the decorator gets executed in isolation.

Ways of executing code with decorators that do seem to be working normally are:

• Copying an pasting code into the REPL
• Executing the file from the command line using python [script-path]
• Using “Python: Run Selection/Line in Python Terminal” (shift + enter) if the decorator is indented as part of some scope (e.g. within an if statement or within a class definition)

Hence it is only the top level decorators that don’t work with “Python: Run Selection/Line in Python Terminal” (shift + enter) and it seems to be because the lines get evaluated / executed in isolation if they are not part of some indented block or pasted in as a whole. If “Python: Run Selection/Line in Python Terminal” (shift + enter) could be made to work like pasting from the clipboard works, then the problem would be solved.
