How to remove a vector QgsVectorLayer from QGIS python plugin

Question

I managed to add QgsVectorLayer in QGIS through a python plugin, for example:

vl = self.iface.addVectorLayer(uri.uri(), layerName, self.dbConn.getProviderName())

But how can I remove it?

Didn't know that you could actually use this method in a variable assignment. Helped me solve a problem that I didn't know I had :P — TurboGraphxBeige, Jun 23, 2017 at 19:11

Are you on QGIS 1.8? If so, you can remove your vl with:

QgsMapLayerRegistry.instance().removeMapLayers( [vl.id()] )

otherwise:

QgsMapLayerRegistry.instance().removeMapLayer( vl.id() )

And if you are on QGIS 3.0+, replace QgsMapLayerRegistry with QgsProject.

Or if by chance you want to remove all empty layers, check out the Remove Empty Layers plugin.

ok -- note that I just edited the answer to use your vl variable.
