What about something simple like this:

import arcpy

# Local variables:
data_to_delete = "C:\\a.gdb\\t3meta"
Delete_succeeded = "false"

# Process: Delete
arcpy.Delete_management(data_to_delete, "RelationshipClass")<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You should be able to use Delete—Help | ArcGIS for Desktop. The documentation specifically mentions relationship classes: "Deleting a relationship class deletes the row corresponding to that relationship from the relationship table."
