It checks the id() of the objects being compared and returns FALSE if they are same. Whats interactive mode? +1 for the capability to specify ignoring orders for specific keys, and for defining your own diff functions. Another way could be to use json.dumps(X, sort_keys=True) option: import json a, b = json.dumps(a, sort_keys=True), json.dumps(b, sort_keys=True) a == b # a normal string comparison .
