Blender Python Printing Vertex Coordinates of selected Mesh

Below you will find the necessary code to get vertex information for yourself in a few easy steps. Running Blender in debug mode has index visualizer built in to allow you to see index information in realtime.

import bpy
for item in bpy.data.objects:
    
    print(item.name)
    if item.type == 'MESH':
        for vertex in item.data.vertices:
            print(vertex.co)

or

import bpy
for item in bpy.data.objects:
    
    print(item.name)
    if item.type == 'MESH':
        vert_list = [vertex.co for vertex in item.data.vertices]
        for vert in vert_list:
            print(vert)

we can go even further.. print faces(polygons), vertices, indices, face normals

# blender 2.6x
import bpy

current_obj = bpy.context.active_object

print("="*40) # printing marker
for face in current_obj.data.polygons:
    verts_in_face = face.vertices[:]
    print("face index", face.index)
    print("normal", face.normal)
    for vert in verts_in_face:
        print("vert", vert, " vert co", current_obj.data.vertices[vert].co)

if you need world coordinates, blenderscripting -- matrixworld will be a good place to find information. Compare the following snippet with the previous one.
