If you really need to pass the function name :
In [3]: def my_func(x):
...: return 2*x
In [4]: def caller(fname,x):
...: return eval("%s(%f)"%(fname,x))
In [5]: caller("my_func",2)

parameter list to be called from within the amoeba function. Simply
passing the name as a string doesn't work since python doesn't know it
