Is it possible to call functions using getattr. I have written a simple script with functions that call either SSL, TLS or plain functionality.
something like: def func(): ...
def funcSSL(): ...
def funcTLS(): ...
Now, based on my args I would like to call either one of them. In my case, I can't seem to figure out what my object would be when I call getattr(object, 'func'+<encryption>) !

From within the module:
encryption = ... f = globals()["func" + encryption] f(...)
In other modules, assuming the module containing the function is called 'module':
import module
encryption = ... f = getattr(module, "func" + encryption) f(...)

A function is an attribute of the module that the function is defined in. If you don't want to hard-code the name of the module, you can use the fact that the name __name__ is bound to the current module, and sys.modules provides a mapping from module names to the actual module objects.
So: getattr(foomodule, 'func' + encr) or: getattr(sys.modules[__name__], 'func' + encr)
Or, in the same module you could have:
encrfuncdict = { 'SSL': funcSSL, # etc }
and your call would be encrfuncdict[encryption](arg1, arg2, ...)
*AND* folk reading your code wouldn't have to write in and ask what all that getattr() stuff was doing ;-)
