я использую vscode для python3 в Ubuntu. Линии с закорючками перестали работать для Python (работает и для других языков). И я использую расширение Microsoft Python.
vscode v1.41.1 Ubuntu v18.04

это то, что я пробовал:

• Я подумал, может быть, это потому, что я установил анаконду, поэтому удалил ее, но не исправил.
• затем я переустановил код vs после удаления его конфигурации из .config/code, но это тоже не сработало.
• также установите для python linting значение true из палитры команд

он не показывает строки с волнистыми линиями ошибок:

вот вклад расширения Microsoft python в отношении линтинга (извините за плохую читабельность):

как заставить волнистые линии снова работать?
