That's only becuase it was asked to go up 1 frame, and not 2.  


def makeVars(**nameVals):
    sys._getframe(2).f_locals.update(nameVals) # <- get 2 frames up.

    
def test():
    try: b
    except NameError: print "Before makeVars: NameError"
    else: print "Before makeVars: Not NameError"
    makeVars(b=2)
    try: b
    except NameError: print "After makeVars: NameError"
    else: print "After makeVars: Not NameError"

	
import sys
test()

>>> 
Before makeVars: NameError
After makeVars: Not NameError
>>>
