Python Operators: Arithmetic,Comparison,logical,Bitwise,Identity and Membership Operators in Python
In this python series you will learn about different types of python operators , Syntax with an Examples. Let's Start
In python have Seven main Operators, there are
These are seven different types of operators in Python.
Let's see one by one. Before we should know
What are Operators in Python?
Generally Operators are special symbol in the python. Also you should know what is Operands? let's see example you can easy understand.
Example:
>>>2+8
10
In above example, '+" plus symbol is a Operator and "2 " and "8" are Operands.
Let's see different types of Operators one by one.
1. Arithmetic Operator:
Arithmetic Operators perform mathematical operation such as Addition, Subtraction, Multiplication and Division. Not only these also Modulo, Exponential.
|
Operator |
Meanings |
Example |
|
+ |
Adds two operands or unary plus |
2+5 7 |
|
- |
subtracts two operands or unary minus |
10-5 5 |
|
* |
Multiple two operands |
2*3 6 |
|
/ |
Divide left operand with right. This result always float values. |
6/2 3.0 |
|
% |
Remainder value of division |
5/2 1 #Remainder value |
|
// |
Divide and shows the result as whole value |
7/3 2 # exact value 2.33 |
|
** |
It is Exponential operator |
2**3 8 |
#Arithmetic program
|
x =
17 y = 4 print('x + y =',x+y) print('x - y =',x-y) print('x * y =',x*y) print('x / y =',x/y) print('x // y =',x//y) print('x
** y =',x**y) |
Output
x + y = 21
x - y = 13
x * y = 68
x / y = 4.25
x // y = 4
x ** y = 83521
2. Comparison Operators
Comparison Operators are compare the value. It returns either True or False depends upon our conditions.
|
Operators |
Meaning |
Example |
|
> |
Greater
than True
if left operand greater right operand, otherwise false |
3>2 True 2>3 False |
|
< |
Lesser
than True
if right operand lesser than left operand Otherwise
false |
1<2 True 17<10 False |
|
== |
Equal
to True
both left and right operand value equal |
3==3 True 4==3 False |
|
!= |
True
if left is not equal to right operands |
X=10,Y=2 True |
# Example Program Comparison
|
x =
7 y =
12 #
It returns true or false. # If condition is true it returns true otherwise false print('x > y is',x>y) print('x < y is',x<y) print('x == y is',x==y) print('x != y is',x!=y) print('x >= y is',x>=y) print('x
<= y is',x<=y) |
Output:
x > y is False
x < y is True
x == y is False
x != y is True
x >= y is False
x <= y is True
3. Logical Operators
|
Operators |
Meaning |
|
AND |
True
if both operands are true |
|
OR |
True
if either of the operand true |
|
NOT |
True
if operands are false |
#Example
AND:
x = 1
print (x > 3 and x < 10)
Output:
True
OR:
x = 7
print(x > 3 or x < 4)
Output:
True
NOT:
x = 7
print(not(x > 3 and x < 10))
Output:
False
4. Bitwise Operators
In python, Bitwise operators are first integer convert into binary
form after operations will perform bit by bit. These are the bitwise operators in Python. In below example,
7=0111 and 5=0101
In above image,
a | b operator, 1+1=1,1+0=1,1+1=1 --> 111-->7
a & b operator, 1+1=0, 1+0=0, 1+1=1 -->101-->5
a ^ b operator, 1+1=0(1+1=1, after 1 change to 0 similarly, 1+0=0 it changes to 1)
As a result, 0010 is the value 2
|
Operators
|
Meaning
|
|
&
Bitwise AND x
& y | Bitwise OR x | y ~ Bitwise NOT ~x ^ Bitwise XOR x ^ y >>
Bitwise right shift x>> <<
Bitwise left shift x<< |
|
|
#Bitwise
Operators Example Program a =
7 #0111 b =
4 #0100 #
Print bitwise AND operation print("a
& b =", a & b) #
Print bitwise OR operation print("a
| b =", a | b) #
Print bitwise NOT operation print("~a
=", ~a) #
print bitwise XOR operation print("a
^ b =", a ^ b) |
Output:
a & b = 4
a | b = 7
~a = -8
a ^ b = 3
Shift Operators
>> Bitwise right shift x >> 2 = 2 (0000 0010)
<< Bitwise left shift x << 2 = 40 (0010 1000)
5. Assignment Operator
Assignment Operators are used to assign a values to a variable. These are assignment operators in Python.
6. Identical Operators:
In Python have two identical operators. There are “Is “and “Is not”
Operators.
IS #True if the operands are identical which means same object.
IS NOT #True if the operand are not identical which means does not same object.
Example:
X=7
X is 7
Output:
True
X=7
X is not 7
Output: False
7. Membership Operators
In python, Membership Operators are used to check if value or
variable in the sequences (Lists, Tuples, Dictionary, Sets).
Upcoming Topics we will learn about Python Data Types.
Python has two Membership Operators.
1. 1. In # True if it finds the element in the sequences.
2. 2. In Not # True if it does not find the
element in the sequences.
Examples:
X= [2,4,6,8,10]
>>> 6 in X
True
>>>3 in not X
False
#Program Example
|
x = ["python", "Hrs"] print("python" in x) print(1 in x) # returns True because a sequence with the value "python" is in the list #
similary, 1 is not in x so it returns false. |
