""" \""" """ evaluates to ' """ ' (as expected), but without the surrounding spaces, """\"""""" evaluates to '"' instead of '"""'.

Is this expected behavior? If I'm reading the definition of string syntax in https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals correctly, it shouldn't be.

[serhiy-storchaka]

"""\"""""" is parsed as """\"""" "": a triple-quoted string containing an escaped '"', followed by an empty single-quoted string.

Oh, right, of course! Sorry and thanks for taking the time to clarify that :)
