#Here is the Python code you requested.

    """Escapes command line arguments for MSVS.
    The VCProj format stores string lists in a single string using commas and
    semi-colons as separators, which must be quoted if they are to be
    interpreted literally. However, command-line arguments may already have
    quotes, and the VCProj parser is ignorant of the backslash escaping
    convention used by CommandLineToArgv, so the command-line quotes and the
    VCProj quotes may not be the same quotes. So to store a general
    command-line argument in a VCProj list, we need to parse the existing
    quoting according to VCProj\s convention and quote any delimiters that are
    not already quoted by that convention. The quotes that we add will also be
    seen by CommandLineToArgv, so if backslashes precede them then we also have
    to escape those backslashes according to the CommandLineToArgv
    convention.
    Args:
    s: the string to be escaped.
    Returns:
    the escaped string.
