functions without parentheses

[Jerry He]

Hi, 
  Is it possible to create a function that you can use
without parenthesizing the arguments? for example, for

def examine(str):
     .....
     .....

Is there some way to define it so that I can call it
like

examine "string" 
instead of examine("string")? 

thanks in advance

-Jerry
