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) Out[5]: 4.0
The better way to do this is: import inspect def call_this(fname, x): caller_frame = inspect.currentframe().f_back f = caller_frame.f_locals.get(fname, caller_frame.f_globals.get(fname)) return f(x) IMPORTANT USAGE NOTE: never do this :-) -- Nathaniel
