Python 2.1 and up, actually.  As mentioned at :
 "A new implementation-dependent function, sys._getframe([depth]), 
  has been added to return a given frame object from the current 
  call stack. sys._getframe() returns the frame at the top of the 
  call stack; if the optional integer argument depth is supplied, 
  the function returns the frame that is depth calls below the top 
  of the stack. For example, sys._getframe(1) returns the caller's 
  frame object.
