QGIS 3.8 Python merge files

Question

For a merge operation I need a list of all my layers in the TOC with path and filename. How can I achieve that?

layers = QgsProject.instance().mapLayers() # dictionary
myLyrList[]
for layer in layers.values():
   print(layer.name())
#Here I need a List of the my layers in the toc with the path and the filename
processing.run("native:mergevectorlayers", {'LAYERS':['/home/lissiklaus/Downloads/2.shp|layername=2','/home/lissiklaus/Downloads/3.shp'],'CRS':QgsCoordinateReferenceSystem('EPSG:31468'),'OUTPUT':'TEMPORARY_OUTPUT'})

Answer 1

You can do that with following modifications in your script.

layers = QgsProject.instance().mapLayers() # dictionary

for layer in layers.values():
   print(layer.name())

list_layers = list(layers.values())

crs = list_layers[0].crs()

#Here I need a List of the my layers in the toc with the path and the filename
processing.runAndLoadResults("native:mergevectorlayers", 
                             {'LAYERS':list_layers,
                             'CRS':crs,
                             'OUTPUT':'TEMPORARY_OUTPUT'})

I tried above script out and it worked as expected.
