Hi,
The code in my last post got line wrapped which will break if directly
tried out. To avoid possible confusion I paste a version below with
shorter lines which should avoid the problem:
import gc, itertools
def names_of(obj):
"""Try to find the names associated to a given object."""
#Find dict objects from the garbage collector:
refs_dicts = (ref for ref in gc.get_referrers(obj)
if isinstance(ref, dict))
#Get a single chained generator for all the iteritems() iterators
#in all the dicts
keyvalue_pairs = itertools.chain.from_iterable(
refd.iteritems() for refd in refs_dicts)
#Return a list of keys (names) where the value (obj) is the one
#we're looking for:
return [k for k, v in keyvalue_pairs if v is obj]
x = []
y = x
z = [x]
print names_of(z[0])
