 the prefix 0x specifies that the value is hexadecimal in nature. when we convert this hexadecimal value to binary form, we get the result as: ‘0b1000’.

 the binary value of 0x35 is 110101 and that of 0x75 is 1110101. on or- ing these two values we get the output as: 1110101, which is equal to 117. hence the result of the above expression is 117.

 in most cases the value of two’s

 bitwise xor gives 1 if either of the bits is 1 and 0 when both of the bits are 1.

 ^ is the xor operator. the binary form of 4 is 0100 and that of 12 is 1100. therefore, 0100^1100 is 1000, which is equal to 8.

 let us consider an example wherein a=2. the binary form of 2 is 0010. when we left shift this value by 2, we get 1000, the value of which is 8. hence if we want to multiply a given number ‘a’ by 4, we can use the expression: a<<2.

 the binary form of -44 is 00101100. the one’s complement of this value is 11010011. on adding one to this we get: 11010100 (two’s complement).

 the expression not(10<20) returns false. the expression not(10>30) returns true. the and operation between false and true returns false. hence the output is false.

 range(0) is empty.

 object of type float cannot be interpreted as an integer.
