Can someone help me understand Binary XOR

Why is the output 0b10 a = 0b1011 b = 0b1001 print(bin(a ^ b)) The third element in both a and b are 1. So shouldn’t the output be 0b00 since it’s XOR which is 1 ^ 1 = 0

XOR returns true if and only if either of bits are 1 but not both. So 1^1 = 0 0^0=0 But 1^0=1 So in your example Leftmost bits are both 1 so 1^1=0 Then second leftmost bits are both 0, so 0^0=0 Third leftmost bits, only one is set, so 1^0=1 And finally last bits are both 1, so 1^1=0 So the result is 0b0010 But then we remove first two zeros as they are meaningless, resulting in 0b10 (it's like when you write 8 instead of 08 or 8.00)
