Selecting by attribute using Python and a list

Question

I have been using this script to select a feature using Python:

layer = iface.activeLayer()
layer.selectByExpression('\"Declividad\"= value', QgsVectorLayer.SetSelection)
selection = layer.selectedFeatures()

But now, I need to select the values for Declividad from a list.

For exemple: list = [10,11,12], so I want to select the values 10,11 and 12 for Declividad.

How could I do that?

Answer 1

You could juse use an expression like:

layer = iface.activeLayer()
my_list = [10, 11, 12]
values = ','.join(str(x) for x in my_list)
layer.selectByExpression('\"Declividad\" IN (' + values + ')', QgsVectorLayer.SetSelection)

• Joseph: @caiovillaca - Most welcome! Glad it helped :)

Answer 2

You can try the IN operator :

layer.selectByExpression('\"Declividad\" IN (\'10\',\'11\','12円')', QgsVectorLayer.SetSelection)

Or do u need to dynamically reference the list name ?

• Kajo: yep, I need it to read the values from the list...
