getting the name of a variable

[Daniel Klein]

Assuming the variable is user-defined (not in __builtins__) and is not
local to the function/method...

>>> x = 42
>>> y = ['a','b','c']
>>> def varname(var):
	print str(var) + " : " + str(globals()[var])

>>> varname('x')
x : 42
>>> varname('y')
y : ['a', 'b', 'c']
>>>
