Here's a snippet for `after/syntax/python.vim` that doesn't cover python 2 or multi-letter cases like `fr\"`. Maybe such an approach could be added in a more complete way to support this, if there is interest.\r\n\r\n```vim\r\nsyn match pythonStringModifier '\\\u003c[brf]\"'me=e-1 contained\r\nsyn region pythonFString   start=+[fF]'+ skip=+\\\\\\\\\\|\\\\'\\|\\\\$+ excludenl end=+'+ end=+$+ keepend contains=pythonBytesEscape,pythonBytesEscapeError,pythonUniEscape,pythonUniEscapeError,@Spell,pythonStringModifier\r\nsyn region pythonFString   start=+[fF]\"+ skip=+\\\\\\\\\\|\\\\\"\\|\\\\$+ excludenl end=+\"+ end=+$+ keepend contains=pythonBytesEscape,pythonBytesEscapeError,pythonUniEscape,pythonUniEscapeError,@Spell,pythonStringModifier\r\nsyn region pythonFString   start=+[fF]'''+ skip=+\\\\'+ end=+'''+ keepend contains=pythonBytesEscape,pythonBytesEscapeError,pythonUniEscape,pythonUniEscapeError,pythonDocTest,pythonSpaceError,@Spell,pythonStringModifier\r\nsyn region pythonFString   start=+[fF]\"\"\"+ skip=+\\\\\"+ end=+\"\"\"+ keepend contains=pythonBytesEscape,pythonBytesEscapeError,pythonUniEscape,pythonUniEscapeError,pythonDocTest2,pythonSpaceError,@Spell,pythonStringModifier\r\nsyn region pythonBytes    start=+[bB]'+ skip=+\\\\\\\\\\|\\\\'\\|\\\\$+ excludenl end=+'+ end=+$+ keepend contains=pythonBytesError,pythonBytesContent,@Spell,pythonStringModifier\r\nsyn region pythonBytes    start=+[bB]\"+ skip=+\\\\\\\\\\|\\\\\"\\|\\\\$+ excludenl end=+\"+ end=+$+ keepend contains=pythonBytesError,pythonBytesContent,@Spell,pythonStringModifier\r\nsyn region pythonBytes    start=+[bB]'''+ skip=+\\\\'+ end=+'''+ keepend contains=pythonBytesError,pythonBytesContent,pythonDocTest,pythonSpaceError,@Spell,pythonStringModifier\r\nsyn region pythonBytes    start=+[bB]\"\"\"+ skip=+\\\\\"+ end=+\"\"\"+ keepend contains=pythonBytesError,pythonBytesContent,pythonDocTest2,pythonSpaceError,@Spell,pythonStringModifier\r\nsyn region pythonRawString  start=+[rR]'+ skip=+\\\\\\\\\\|\\\\'\\|\\\\$+ excludenl end=+'+ end=+$+ keepend contains=pythonRawEscape,@Spell,pythonStringModifier\r\nsyn region pythonRawString  start=+[rR]\"+ skip=+\\\\\\\\\\|\\\\\"\\|\\\\$+ excludenl end=+\"+ end=+$+ keepend contains=pythonRawEscape,@Spell,pythonStringModifier\r\nsyn region pythonRawString  start=+[rR]'''+ skip=+\\\\'+ end=+'''+ keepend contains=pythonDocTest,pythonSpaceError,@Spell,pythonStringModifier\r\nsyn region pythonRawString  start=+[rR]\"\"\"+ skip=+\\\\\"+ end=+\"\"\"+ keepend contains=pythonDocTest2,pythonSpaceError,@Spell,pythonStringModifier\r\n\r\nhi link pythonStringModifier Operator\r\n```\r\n","author":{"url":"https://github.com/adigitoleo","@type":"Person","name":"adigitoleo"},"datePublished":"2023-08-07T15:43:39.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/95/python-syntax/issues/95"}
