How can I add a Vertex from a script? I'd like to create a line from the extrusion of a vertex. This is my script now:

import bpy

location = bpy.context.scene.cursor_location    # Get Cursor location
bpy.ops.object.editmode_toggle()                # Enter Edit Mode

# Here goes the script I'm looking for!

bpy.ops.mesh.extrude_region_move()              # Extrude vertex

First of all you have to create a object and a mesh, after that you can add the vertex to it:

# name: string for new object name
# verts: array of position coords - [(-1.0, 1.0, 0.0), (-1.0, -1.0, 0.0)]

def create_Vertices (name, verts):
    # Create mesh and object
    me = bpy.data.meshes.new(name+'Mesh')
    ob = bpy.data.objects.new(name, me)
    ob.show_name = True
    # Link object to scene
    bpy.context.scene.objects.link(ob)
    me.from_pydata(verts, [], [])
    # Update mesh with new data
    me.update()
    return ob
