So long as the OP doesn't care if they get no names or several name that
might not matter. However, explicitly passing in the name you want to use
is likely to be more useful.
>>> def getcallersnames(obj):
f = inspect.currentframe().f_back.f_back
return [name for name in f.f_locals if f.f_locals[name] is obj]
>>> def bip(x):
print getcallersnames(x)
>>> def foo(bar):
baz = bar
bip(baz)
bip(baz+1)
>>> foo(3)
['bar', 'baz']
[]
>>> bip(bip)
['bip']
