How do you manipulate an image with Python-Fu (console) in Gimp 3?

[joeyeroq]

I just installed gimp 3.0 and wanted to test the Python Console.
For example, in Gimp 2.10 you could print the layers of an image with this code in the console:

Code:

img = gimp.image_list()[0]
for layer in img.layers:
    print(layer.name)

How do you do this in Gimp 3?
