okay after some investication i voked out that you can't use a universal forwarder with phyton scripts!!
Read the note below:
Scripted inputs and Python
Full Splunk comes bundled with Python. The universal forwarder does not. Therefore, if you're currently using scripted inputs with Python and you want to use those scripts with the universal forwarder, you must first install your own version of Python. If you have been using calls specific to Splunk's Python libraries, you cannot do so with the universal forwarder, since those libraries exist only in full Splunk. You may use other scripting languages for scripted inputs with the universal forwarder if they are otherwise supported on the target host (for example, Powershell on Windows Server 2008.)
Now i must find out which forwarder is needed????
