Do I really need to mention that the whole concept here is broken. This
only works if you call it from global scope. If you call it from inside a
function it [usually] won't work:
>>> def makeVars(**nameVals):
sys._getframe(1).f_locals.update(nameVals)
>>> 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: NameError
>>>
