getting the name of a variable

[Daniel Klein]

Forgot to mention, if var cannot be found in the globals() dicitonary,
it will throw a KeyError exception. A slight modification to the
function will handle this

>>> def varname(var):
	var = str(var)
	try:
		print var + " : " + str(globals()[var])
	except KeyError:
		print var + " : <undefined>"
	
>>> varname('zz')
zz : <undefined>
