Description

The Shift + Enter shortcut ("Send Selection To Interactive Window") allows you to send small executable blocks of code to your terminal. This is helpful when you want to execute just one line or function and not your entire file.

For example, if you have a function

def foo():
    print("A")

    print("B")

and just put your cursor on the def foo(): line (or select the entire function code), the function defenition of foo() will be sent to your terminal and executed. VSCode does this in a smart way which ensures that you do not get an IndentationError: unexpected indent like you would get if you just copy-pasted the function definition in the terminal.

This breaks if you include triple quotes (""") or (''') anywhere in your function. VSCode still recognizes the entire function as the entity it wants to execute, and tries to send it to the terminal, but now fails to handle empty lines smartly and raises an IndentationError: unexpected indent.

It does not matter whether the pythonREPLSmartSend setting is enabled or not.

Steps to Reproduce:

1. Create a new python file
2. Define a function in which a new line occurs, e.g.

def this_works():
    print("A")

    print("B")

3. Put your cursor on the function definition or select the function and press Shift + Enter
4. This handles the empty line well and defines the function in your terminal
5. Define a function in which a triple quote occurs, e.g.

def this_breaks_a():
    """This function breaks"""
    print("A")

    print("B")

or even

def this_breaks_b():
    print("A ''' B")

    print("B")

6. Put your cursor on the function definition or select the function and press Shift + Enter
7. VSCode sends the code to your Terminal, but raises an IndentationError: unexpected indent

From what I can tell, this works in the interactive window but breaks in the terminal.
I assume because the terminal is getting the lines one at a time, and the blank line makes it think the code is finished and should be run (because of the new >>> on the errored line).

@epistoteles Thanks for filing this issue: looks like dup of #24069
Lets track it in #24069

Can folks please try the latest pre-release version of the Python extension and let me know if the problem is resolved?
Want to make sure before deploying reverted changes to stable. - Thanks
