how can I get the name of a variable (or other object)?

[Richard Oudkerk]

Try

def printvars(varlist):
     allvars = globals()
     allvars.update(locals())
     for var in varlist:
         print [ n for n in allvars if allvars[n] is var ], "=>", var

a = 10
b = 20
c = 30
d = a
e = "hello"

printvars([a,b,e, 143, printvars, None])

It gives the output

['a', 'd'] => 10
['b'] => 20
['e'] => hello
[] => 143
['printvars'] => <function printvars at 0xa0c53e4>
['__doc__'] => None

I want to print the variable together with it's name, for a list of variables, 
then it could make sense:
