Through Python3(About Operators)

Hola Everyone, Today we will be talking about Operators in Python. Operators are special symbols in Python that carry out arithmetic or logical computation. Operators are used to performing operations on values and variables. Operators can manipulate individual items and returns a result.

There are many operators in Pythons:

• Arithmetic operators: Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, and division.

Operator	Description	Syntax
+	Addition: adds two operands	x + y
–	Subtraction: subtracts two operands	x – y
*	Multiplication: multiplies two operands	x * y
/	Division (float): divides the first operand by the second	x / y
//	Division (floor): divides the first operand by the second	x // y
%	Modulus: returns the remainder when first operand is divided by the second	x % y

• Relational Operators: Relational operators are used to compare the values. They either return True or False according to the condition.

Operator	Description	Syntax
>	Greater than: True if the left operand is greater than the right	x > y
<	Less than: True if the left operand is less than the right	x < y
==	Equal to: True if both operands are equal	x == y
!=	Not equal to – True if operands are not equal	x != y
>=	Greater than or equal to: True if the left operand is greater than or equal to the right	x >= y
<=	Less than or equal to: True if the left operand is less than or equal to the right	x <= y

• Logical operators: Logical operators are used to perform Logical AND, Logical OR and Logical NOT operations.

Operator	Description	Syntax
and	Logical AND: True if both the operands are true	x and y
or	Logical OR: True if either of the operands is true	x or y
not	Logical NOT: True if the operand is false	not x

• Bitwise operators: Bitwise operators act on bits and performs bit by bit operation.

Operator	Description	Syntax
&	Bitwise AND	x & y
|	Bitwise OR	x | y
~	Bitwise NOT	~x
^	Bitwise XOR	x ^ y
>>	Bitwise right shift	x>>
<<	Bitwise left shift	x<<

• Assignment operators: Assignment operators are used to assign values to the variables.

Operator	Description	Syntax
=	Assign value of right side of expression to left side operand	x = y + z
+=	Add AND: Add right side operand with left side operand and then assign to left operand	a+=b     a=a+b
-=	Subtract AND: Subtract right operand from left operand and then assign to left operand	a-=b       a=a-b
*=	Multiply AND: Multiply right operand with left operand and then assign to left operand	a*=b       a=a*b
/=	Divide AND: Divide left operand with right operand and then assign to left operand	a/=b         a=a/b
%=	Modulus AND: Takes modulus using left and right operands and assign result to left operand	a%=b   a=a%b
//=	Divide(floor) AND: Divide left operand with right operand and then assign the value(floor) to left operand	a//=b       a=a//b
**=	Exponent AND: Calculate exponent(raise power) value using operands and assign value to left operand	a**=b     a=a**b
&=	Performs Bitwise AND on operands and assign value to left operand	a&=b     a=a&b
|=	Performs Bitwise OR on operands and assign value to left operand	a|=b         a=a|b
^=	Performs Bitwise xOR on operands and assign value to left operand	a^=b       a=a^b
>>=	Performs Bitwise right shift on operands and assign value to left operand	a>>=b     a=a>>b
<<=	Performs Bitwise left shift on operands and assign value to left operand	a <<= b                    a= a << b

Special operators: There are some special type of operators like-

• Identity operators-
  is and is not are the identity operators both are used to check if two values are located on the same part of the memory. Two variables that are equal does not imply that they are identical.

  is          True if the operands are identical 
  is not      True if the operands are not identical

• Membership operators–
  in and not in are the membership operators; used to test whether a value or variable is in a sequence.

  in            True if value is found in the sequence
  not in        True if value is not found in the sequence
