Can someone explain the ^= operator to me?

Question

I've been searching and found that the ^= operator is the same as running the function ixor(a,b,). However this returns the sum of a and b, so then how is ^= different than +=?

Thanks!

Also try `set(range(1,3)) ^ set(range(2,4))` – inspectorG4dget May 01 '15 at 03:52 — inspectorG4dget, May 01 '15 at 03:52

The carat ^ is bitwise XOR. Imagine it like this:

>>> 8^3
11

8 in binary: 1000
3 in binary: 0011
8^3:         1011

x ^ y

Does a bitwise exclusive or. Each bit of the output is the same as the corresponding bit in x if that bit in y is 0, and it's the complement of the bit in x if that bit in y is 1. source
