Just trap the no_data_found exception
begin
<your select into>
exception
when no_data_found then <take appropiate action>; end;

Of course this is documented in the PL/SQL manuals. The other solution, not taking into account the NO_DATA_FOUND exception, would set the number of records to 0, if the TOO_MANY_ROWS exception occurs.
Consequently, it misses the point and it is incorrect.
