However, the text written inside triple quotes (''' or ''"") is also considered as comment. You can use
the triple quotes to write multiline comments. For example:
'''This is """This is

OPERATORS
In Python, operators can be defined as special symbols which perform arithmetic and logical
computation. The values which the operators use to get the output are called operands. For
example, in the expression 10–5, 10 and 5 are operands and the minus (–) sign is the operator.
Let us learn about various Python operators.
Arithmetic Operators
Arithmetic operators perform arithmetic operations between two operands. The arithmetic
operators are defined in the following table:
Operator Name Description Example Output
(x=7 and
y=3)
+ Addition Adds values on either side of the operator. x + y 10
Subtraction Subtracts right hand operand from left x – y 4
–
hand operand.
Multiplication Multiplies values on either side of the x * y 21
*
operator.
Division Divides left hand operand by right hand x / y 2.33
/
operand.
Modulus Divides left hand operand by right hand x % y 1
%
operand and returns remainder.
Exponentiation Performs exponential (power) calculation x ** y 343
**
on operands.
Floor or Integer Divides and cuts the fractional part from x // y 2
//
division the result.
