Is there something in Python similar to the C++ switch operator?

switch (letters) {
    case 'A': doActionA
    case 'B': doActionB
    case 'C': doActionB
    ...
    default: doDefaultAction
}

Something that can help you to avoid deep if-else nesting and to maintain a flat and linear conditional structure.
