Mr. 12 When using the | operator, you are comparing the 2 sets against each other. Overlapping them in a way. So when you overlap 0b1100 and 0b110, the following occurs as you look at the numbers from the left. 1 => 1 1 1 => 1 0 1 => 1 0 0 => 0 Result is 0b1110 Remember that 1 is true & 0 is false, so if given an option to choose between true and false, the code will return true print(2|3) #3 print(0b10|0b11) #3 =>0b11

Mr. 12 Go through this section to see how set operators work https://www.sololearn.com/learn/JUMP_LINK__&&__Python__&&__JUMP_LINK/2464

I have seen something like this before which was explained as set operators working on the binary format of the numbers. The following snippet may help you understand more print(3|5) print(bin(3)) print(bin(4)) print(bin(5))

Mr. 12 Ahh, the joys of binary numbers. As you discovered, 0b10 is the binary equivilent of 2. Therefore: 0b11 is 3 0b100 is 4 0b101 is 5 print(0b11|0b101) is 0b111 0b111 is 7

Granger thank you bro, i know about binary number but i confused after it is printing 0b11 for 3,which is only 11 or 011 or 0011 for 3 in binary. i just confused with 'b' presenting in 0b11. And also thank your for explaining the arthimatic operators, Now I Got It.

Rik Wittkopp can u explain me more about this? if we join 2 | 3 (0b10 | 0b11) ans would be 0b10 right? because 1 is already there in 0b10? Mr. 12 Ahh, the joys of binary numbers. As you discovered, 0b10 is the binary equivilent of 2. Therefore: 0b11 is 3 0b100 is 4 0b101 is 5 print(0b11|0b101) is 0b111 0b111 is 7

Mr. 12 0 => 0 0 => 0 1 0 => 1 1 1 => 1 Result => 0b11 Same rules apply
