Python/Jupyter笔记本未正确突出显示fstring

Question

下面是Jupyter笔记本和2个Python代码片段的示例：

在Jupyter中，只有当它是一个变量时，它大多数时候都不会高亮显示f字符串，即使它被定义并用作a+b，它也不会高亮显示

在Python中，如果定义了一个变量，它将突出显示该变量，但如果它的值包含任何数学运算，则它只是不一致

我试着检查我的settings.json，但不认为问题出在它上面：

{
  "gitlens.advanced.messages": {
    "suppressShowKeyBindingsNotice": true
  },
  "workbench.iconTheme": "Monokai Pro (Filter Spectrum) Icons",
  "liveServer.settings.donotShowInfoMsg": true,
  "explorer.confirmDelete": false,
  "editor.tabSize": 2,
  "editor.rulers": [110],
  "workbench.startupEditor": "none",
  "editor.snippetSuggestions": "top",
  "workbench.statusBar.visible": true,
  "editor.suggestSelection": "first",
  "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",
  "python.pythonPath": "/opt/anaconda3/envs/abc/bin/python",
  "workbench.colorCustomizations": {
    "editorRuler.foreground": "#e1b525"
},
"python.autoComplete.addBrackets": true,
  "editor.wordWrapColumn": 200,
  "python.formatting.provider": "black",
  "launch": {
    "configurations": [],
    "compounds": []
  },
  "workbench.colorTheme": "One Dark Pro",
  "python.linting.mypyEnabled": true,
  "python.linting.pylintEnabled": true,
  "python.linting.enabled": false,
  "html.format.enable": false,
  "javascript.format.enable": false,
  "typescript.format.enable": false,
  "json.format.enable": false,
  "python.languageServer": "Pylance",
  "python.analysis.completeFunctionParens": true,
"kite.showWelcomeNotificationOnStartup": false,
"jupyter.askForKernelRestart": false,
"jupyter.textOutputLimit": 0,
"jupyter.alwaysTrustNotebooks": true,
"jupyter.sendSelectionToInteractiveWindow": true,
"workbench.editorAssociations": {
  "*.ipynb": "jupyter.notebook.ipynb"
},
"python.defaultInterpreterPath": "/opt/anaconda3/envs/abc/bin/python",
"[python]": {

  "gitlens.codeLens.symbolScopes": [
    "!Module"
  ],
  "editor.wordBasedSuggestions": false
}
}

也许这部分"python.formatting.provider": "black"会有所不同，但据我所知，它只是格式化，而不是突出显示
