Function that knows its argument's variable name

Sun Mar 14 07:58:07 EDT 2010

I want to write function that prints a value of a variable, for
debugging. Like:
with
myVariable = "parrot"
otherVariable = "dead"
probe(myVariable)
probe(otherVariable)
instead of the longer
print "myVariable = ", myVariable
print "otherVariable = ", otherVariable
Is that even possible?
The function would look like
def probe(var):
 nameOfVar = someMagic(var)
 print nameOfVar, " = ", var
but can someMagic(var) find the variable name? Is that possible?
