Q: Name of a arbitary variable as a string?

[username]

Hi! 

Sorry, if this Question was asked a million times!

I am searching for a function (call it: var_name) that do something like
this: 

>>> V="Hello World"
>>> var_name(V)
'V'


I know how to get it from the locals() Dict. but this is not well
defined if I have a second variabe 

>>> T="Hello World" 

Thanks

Marco
