No. Objects have no names. Consider
foo = foobar()
bar = foo
What is that object's name? foo or bar? If you still think it is foo,
consider this:
foo = foobar()
bar = foo
foo = foobar()
Now, the object referenced in bar(), should it's "name" still be foo?
Even though the name foo refers to some other object?
Of course, you can invoke globals() and check whether the object is
listed there.
