Question

How can I run a python script on server A that can add entries to a list-item in another python script on server B? (Needs to be hyperefficient.)

Are there any easy solutions (or modules) that help with this?

Thanks

I use xmlrpclib to call functions remotely.
Make a function that appends values to a global array, then register the function with xmlrpclib and call it from machine B.

It’s pretty easy to use. Here is a good starting point: http://docs.python.org/2/library/xmlrpclib.html#boolean-objects

Made an example:

#!/usr/bin/python
from SimpleXMLRPCServer import SimpleXMLRPCServer
import xmlrpclib

arrayToAppend = []

def appendArray(value):
    global arrayToAppend
    arrayToAppend.append(value)
    return 1

def valueOfArray():
    return arrayToAppend

server = SimpleXMLRPCServer(("localhost", 8000))
print "Listening on port 8000..."
server.register_function(appendArray, "appendArray")
server.register_function(valueOfArray, "valueOfArray")
server.serve_forever()

Then test/use it like so

>>> import xmlrpclib
>>> p = xmlrpclib.Server("http://localhost:8000")
>>> p.appendArray("test1")
1
>>> p.valueOfArray()
['test1']
>>> p.appendArray("test2")
1
>>> p.valueOfArray()
['test1','test2']
>>>
