C++ Else statement in Exception Handling

The concept of an else for a try block doesn't exist in c++. It can be emulated with the use of a flag:

{
    bool exception_caught = true;
    try
    {
        // Try block, without the else code:
        do_stuff_that_might_throw_an_exception();
        exception_caught = false; // This needs to be the last statement in the try block
    }
    catch (Exception& a)
    {
        // Handle the exception or rethrow, but do not touch exception_caught.
    }
    // Other catches elided.

    if (! exception_caught)
    {
        // The equivalent of the python else block goes here.
        do_stuff_only_if_try_block_succeeded();

    }
}

The do_stuff_only_if_try_block_succeeded() code is executed only if the try block executes without throwing an exception. Note that in the case that do_stuff_only_if_try_block_succeeded() does throw an exception, that exception will not be caught. These two concepts mimic the intent of the python try ... catch ... else concept.

Why not just put it at the end of the try block?
