In Python >> is called right shift operator. It is a bitwise operator. It requires a bitwise representation of object as first operand. Bits are shifted to right by number of bits stipulated by second operand. Leading bits as towards left as a result of shifting are set to 0.>>> bin(a)     #binary equivalent 0110 0100 '0b1100100' >>> b=a>>2     #binary equivalent 0001 1101 >>> b 25 >>> bin(b) '0b11001'

The not in operator returns false if object is present in sequence, true if not found>>> 'p' not in 'Tutorialspoint' False >>> 'c' not in 'Tutorialspoint' True >>> 10 not in range(0,5)

In Python, is and is not operators are called identity operators. Each object in computer's memory is assigned a unique identification number (id) by Python interpreter. Identity operators check if id() of two objects is same. 'is not' operator returns true of id() values are different and false if they are same.>>> a=10 >>> b=a >>> id(a), id(b) (490067904, 490067904) >>> a is not b False >>> a=10 >>> b=20 >>> id(a), id(b) (490067904, 490068064) >>> a is not b True

In some languages like C / C++ the "!" symbol is used as a logical NOT operator. !x it returns true if x is false else returns false. The equivalent of this "!" operator in python is logical NOT, It also returns true if the operand is false and vice versa. Example In the Following example the variable operand_X holds a boolean value True, after applying the not operator it returns False. operand_X = True print("Input: ", operand_X) result = not(operand_X) print('Result: ', result) Output Input: True Result: False Example For False value the ...

In Python ** is a raised to operator. It returns x raised to y in the expression x**y>>> x=5 >>> y=3 >>> x**y 125^ is a bitwise XOR operator. Taking two bits as operands it returns 1 if one is 1 and other is 0>>> a=10 >>> bin(a)    #0001 1010 '0b1010' >>> b=20 >>> bin(b)    #0010 0100 '0b10100' >>> c=a^b >>> c   30 >>> bin(c)    #0011 1110 '0b11110'// is defined as floor division operator. It returns integer part of result of division operation>>> 10/3 3.3333333333333335 >>> 10//3 3For negative division, floor rounds towards negative infinity.>>> -10/3 ... Read More

In Python = symbol is defined as assignment operator. It requires one variable on its left and an expression on its right. Value of the expression on right is assigned to variable on left. Expression and name of variable are not interchangeable.>>> a=10 >>> b=20 >>> c=a+b >>> a,b,c (10, 20, 30) >>> a+b=c SyntaxError: can't assign to operatorThe == symbol is a comparison operator and called equal to operator. It returns true if operands on either side are equal, otherwise it returns false>>> 10+2 == 10 False >>> (10+2) == 12 True >>> 'computer' == 'Computer' False >>> 'computer' == "computer" True
