pymel has Callback object class that works well for this purpose.
It works like partial except that it'll ignore any incoming args/kwargs that
are passed when the callback is invoked:
cb = pm.Callback(myFunc, arg1=1)
cb("args", dont='matter')
import pymel as pm
pm.button(l="Test button", c=pm.Callback(myFunc, 1, 2, arg1="a", arg2="b"))

please note that the example I sent are reversed... the first one is
the keywords example, and the second one the non keywords example
