Bitwise XOR between these sets returns "set()": Why?

a = {0, 1} b = {1, 0} print(a ^ b) # prints "set()"

Md. Niamul Ahad Chowdhury ^ operator only includes the unique items from the sets, the items from set a, which don't exists in set b and the items from set b, which don't exist in set a. All items in set a exist in set b and viceverca, so the combined set became empty.

If it printed { }, you could not conclude from the output, whether the printed object was an empty dict or empty set, maybe that's why empty sets are represented as set().

Seb TheS Okay, thank you. But why was it empty in the first place?
