Errors in import multiple csv files into QGIS
I want to import multiple csv files into QGIS 3.2. It shows that "TypeError: QgsProject.addMapLayers(): argument 1 has unexpected type 'QgsVectorLayer'". I am new to QGIS and get confused. Here is my code. Thanks in advance!
import os, glob
path_to_csv = "D:/Paper/Data/bga_new_coord/"
os.chdir(path_to_csv)
for fname in glob.glob('*.csv'):
uri = "file:///" + path_to_csv + fname + "?delimiter=&crs=epsg:28355&xField=&yField=".format(";","xcoord","ycoord")
name=fname.replace('.csv', '')
lyr=QgsVectorLayer(uri, name, 'delimitedtext')
lyr.isValid()
QgsProject.instance().addMapLayers(lyr)
And the Error is
TypeError: QgsProject.addMapLayers(): argument 1 has unexpected type 'QgsVectorLayer'
python qgis

You are using the function addMapLayers() which expects a list of layers (ref) instead of a single layer. Instead, try using addMapLayer() , which expects a layer.
The error you get says basically the same thing: "Unexpectedly, I am being given a QgsVectorLayer (I wanted a list)"

Thanks a lot! You are right, I need to use QgsProject.addMaplayer() rather than addMaplayers(). It works!
