When i tried |, i thought it is addition but 4|4 also give 4? They're called bitwise operators: http://wiki.python.org/moin/BitwiseOperators + is the addition operator: 4 + 2 == 6 4 + 4 == 8 | is the bitwise OR >>> 4|2 6 >>> 4|1 5 >>> 4|3 7 >>> 4|4 4 When i tried ^, looks like subtraction but 2^4 gives 6? ^ is the bitwise XOR - is subtraction >>> 2^3 1 >>> 2^2 0 >>> 2^4^ is the XOR operator 6 Pls help to clear my confusion. thanks. For more information about bitwise operations, wikipedia is your friend! http://en.wikipedia.org/wiki/Bitwise_operation HTH, Wayne
