WebSep 4, 2012 · A remote object may have a different hash code than a local one, even if the two are equal. 3. Do not use hashCode in distributed applications. Moreover, you should be aware that the implementation of a hashCode function may change from one version to another. Therefore your code should not depend on any particular hash code values. WebJul 31, 2016 · Python's hash function is designed for speed, and maps into a 64-bit space. Due to the birthday paradox, this means you'll likely get a collision at about 5 billion entries (probably way earlier, since the hash function is not cryptographical).
