Blender from_pydata error with reading vertex positions from file - arrays

Question

I get the error;
Error: Array length mismatch (expected 3, got 13)
TypeError: a float is required
Traceback (most recent call last):
File "\Test.py", line 393, in from_pydata
File "C:\Program Files (x86)\Blender Foundation\Blender\2.68\2.68\scripts\modules\bpy_types.py", line 393, in from_pydata
self.vertices.foreach_set("co", vertices_flat)
TypeError: couldn't access the py sequence
Error: Python script fail, look in the console for now...
Here is the code:
filePath = "C:\\Users\\siba\\Desktop\\1x1x1.blb"
f = open(filePath)
line = f.readline()
while line:
if(line == "POSITION:\n"):
POS1 = f.readline().replace('\n','')
line = f.readline()
f.close()
coord1 = POS1
Verts = [coord1]
import bpy
profile_mesh = bpy.data.meshes.new("Base_Profile_Data")
profile_mesh.from_pydata(Verts, [], [])
profile_mesh.update()
profile_object = bpy.data.objects.new("Base_Profile", profile_mesh)
profile_object.data = profile_mesh
scene = bpy.context.scene
scene.objects.link(profile_object)
profile_object.select = True
Here is 1x1x1.blb:
POSITION:
0.5 0.5 0.5

Just a stab in the dark, as I don't script Blender and I cannot be bothered to find the docs, but I would imagine Verts needs to be a list of floats, and you are providing a space-separated string, so this might work:
coord1 = POS1.split(' ')
map(float, coord1)
Verts = coord1
