I loaded a GeoPackage into Python and I can't figure out how to list all the layers in the file. How do I do that?

Input: GeoPackage loaded into Python.

Desired output: A list of the layers in the GeoPackage.

Code for connecting to GeoPackage:

import geopandas as gpd    
gpkg = 'path/to.gpkg'
# Missing: list layers

    What code did you use to load the Geopackage into Python?

    That looks like it just sets a string variable to a full path name representing the GeoPackage file. I thought you must have been creating a GeoPackage object using something, and just didn't know how to access a property with its layers .

It's simple to do this using Fiona. I prefer using GeoPandas to read the Geopackage, and then Fiona to list the layers:

import geopandas as gpd
import fiona

gpkg = 'path/to.gpkg'
layers = fiona.listlayers(gpkg)

You'll end up with the layer names as a list.

Using the GeoDjango API you can do the following:

from django.contrib.gis.gdal import DataSource

gpkg = DataSource('path/to.gpkg')
layers = [layer.name for layer in gpkg]
