Example:
Program : Output :
# printing a string Hello World
#print five names Rachna
print("Hello World") Sambhav
print("Rachna") Akshat
print("Sambhav") Tushar
print("Akshat")
print("Tushar")
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
Multiline OR Multiline
Comment''' Comment"""
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.
Python divides the operators in the following categories.
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 the right-hand operand from the x – y 4
left-hand operand.
* Multiplication Multiplies values on either side of the operator. x * y 21
/ 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 the remainder.
** Exponentiation Performs exponential (power) calculation on x ** y 343
operands.
// Floor or Integer Divides left-hand operand by right-hand x // y 2
division operand and round off the result to the
nearest whole number.
