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 ;-)
