I'd suggest getattr():
>>> import sys
>>> xt = getattr(sys,exit)
>>> xt()
Alternatively, if its a fixed set of options
(and it sound as if it is) set up a dictionary:
funcs = {'exit': sys.exit, size: sys.getsizeof)
xt = funcs('exit')
xt()
Which has the advantage of providing a menu
of friendly function names to the user:
for func in funcs:
print(func)
fn = input('choose a function from the list above')
And allows you to validate the selection
if fn in funcs.keys():
f = funcs[fn]
else: print(...)
