runs.start() deletes its own run with run.delete(), which takes
no arguments. Inside a with block, leave the block right after: the deleted run accepts no more work.
Example
Parameters
string
required
The ID of the run to delete.
The sessions of the run stay, and so does everything else that scored them. A monitor’s scores of the
same sessions survive, and a session scored by two runs keeps the scores of the other run.
