Python Operator concept

Python Operator Concept:-

It is used to perform operation using operand ,operand can be variable,constant and literals ,Python has multiple operator similar to c language to implement mathematical, logical ,conditional and comparison operation.

all operator of PYTHON  has been defined as a predefine method which is called magic function in python.

for example if we use + operator then it will call to def __add__(): to perform addition between two number's.

Type of operator:-

1) Arithmetic:-      +, - , *, /(true division), // (floor division) ,%,** power

Example of Arithmetic operator:-

2) Conditional or Relational :-  It is used to solve condition based problem that condition is true or false.

 <    Less then
<=   Less then equal to
>     Greater then
>=    Greater then equally

3) Comparison Operator:-   it is used to compare two different value

!= not equal to
== equal to

4) Assignment Operator:-  It is used to assign the value of variable in program.

a=5  means 5 value will be assign into a

4.1)  Simple Assignment


4.2)  Complex Assignment:-  we can assign data as well as perform other operation

        +=      a+=2  or  a=a+2
        -=       a-=5   or  a=a-5
       *=       a*=5   or  a=a*5
       /=        a/=3    or a=a/3
      //=        a//=4   or a=a//4

5) Logical Operator:-   It is used to manage multiple statements under conditional statements and return true and false value.

and :-   it will return true when all condition will be true

   a>b and a>c   it means a should be greater b and c both

or :-  it will return true when particular condition will be true

  a>b or a>c

not:-  it is just opposite of true statement.

6) identity operator :-

  is       :-   it will return true when variable will point to same address.

  is not  :-  it is opposite of "is operator".

7) Membership operator :-

 in :-  It will return true when element will be exist on List

 not in :-  It is just opposite .
