Data Conversion Failed from String to Line

I and a teammate tried to collect the xyz data of the kinect and then we tried to import through a tcp client written in rhino.python to grasshopper. The problem is that the data comes as a string, is there any string to number add-on or anyone can help us, we are new in grasshopper and python, we will be very happy for every answer.

Best greetings,

richard and sebastian

Can you post an example of the data coming in?

I can't see much detail in that image.

if the data is a series of XYZ numbers, delimited by commas:

2,4,3
2,4.2,3.5

2.3,4.5,4.1

then you can convert one line into a point like so:

import Rhino
numbers = [float(n) for n in incomingXYZstring.split(',')]

point = Rhino.Geometry.Point3d(*numbers)

I don't think that Grasshopper has an ascii to string converter, but this is generally very easy in python, or any other programming language. In python if 'x' represents the integer of an ascii character, then 'chr(x)' will return the corresponding letter/character.
