Operator in python

   Operator : operator which operator on operands ,its symbol  used to calc,compare,assign

   operand:   operand constant and variable in programming instruction

      x=y+2

      varible x,y
      constant--2

      operator ===>+,=

Types of operator

1)Arithmetic operator
   +,-,,/ ,//(floor division),*(exponent)
   %(remainder)

2)Relational/Comparision operator
  <,<=,>=,==,!=

3)* Logical operators
    &&,||,!===C/C++/java
//change
    and,or,not---> keywords operator level

4) bitwise operator
   &,|,~ ^,>>,<<

5) Assignment operator
  =
   //shorthand
    +=,-= ,=,/=,//=,*=
    &=,/=,^=,>>=,<<=
    //special operator
