Python Operators
Operators and Operands
In computer programming languages operators are special symbols which represent computations, conditional matching etc. The values the operator uses are called operands.
c = a + b Here a and b are called operands and '+' is an operator
Python supports following operators.

Python Arithmetic Operators
Operator | Name | Example | Result |
---|---|---|---|
+ | Addition | x+y | Sum of x and y. |
- | Subtraction | x-y | Difference of x and y. |
* | Multiplication | x*y | Product of x and y. |
/ | Division | x/y | Quotient of x and y. |
% | Modulus | x%y | Remainder of x divided by y. |
** | Exponent | x**y | x**y will give x to the power y |
// | Floor Division | x/ y | The division of operands where the result is the quotient in which the digits after the decimal point are removed. |
See the following statements in Python Shell.

Python Comparison Operators
Operator | Name | Example | Result |
---|---|---|---|
== | Equal | x==y | True if x is exactly equal to y. |
!= | Not equal | x!=y | True if x is exactly not equal to y. |
> | Greater than | x>y | True if x (left-hand argument) is greater than y (right-hand argument). |
< | Less than | x<y | True if x (left-hand argument) is less than y (right-hand argument). |
>= | Greater than or equal to | x>=y | True if x (left-hand argument) is greater than or equal to y (left-hand argument). |
<= | Less than or equal to | x<=y | True if x (left-hand argument) is less than or equal to y (right-hand argument). |
See the following statements in Python Shell.

Python Logical Operators
Operator | Example | Result |
---|---|---|
and | (x and y) | is True if both x and y are true. |
or | (x or y) | is True if either x or y is true. |
not | (x not y) | If a condition is true then Logical not operator will make false. |
See the following statements in Python Shell.

Python Assignment Operators
Operator | Shorthand | Expression | Description |
---|---|---|---|
+= | x+=y | x = x + y | Adds 2 numbers and assigns the result to left operand. |
-= | x-= y | x = x -y | Subtracts 2 numbers and assigns the result to left operand. |
*= | x*= y | x = x*y | Multiplies 2 numbers and assigns the result to left operand. |
/= | x/= y | x = x/y | Divides 2 numbers and assigns the result to left operand. |
%= | x%= y | x = x%y | Computes the modulus of 2 numbers and assigns the result to left operand. |
**= | x**=y | x = x**y | Performs exponential (power) calculation on operators and assign value to the equivalent to left operand. |
//= | x//=y | x = x//y | Performs floor division on operators and assign value to the left operand. |
See the following statements in Python Shell.

Python Bitwise Operators
Operator | Shorthand | Expression | Description |
---|---|---|---|
& | And | x & y | Bits that are set in both x and y are set. |
| | Or | x | y | Bits that are set in either x or y are set. |
^ | Xor | x ^ y | Bits that are set in x or y but not both are set. |
~ | Not | ~x | Bits that are set in x are not set, and vice versa. |
<< | Shift left | x <<y | Shift the bits of x, y steps to the left |
>> | Shift right | x >>y | Shift the bits of x, y steps to the right. |
# Each step means 'multiply by two'
* Each step means 'divide by two'
Conditional Operators
Conditional expressions or ternary operator have the lowest priority of all Python operations. The expression x if C else y first evaluates the condition, C (not x); if C is true, x is evaluated and its value is returned; otherwise, y is evaluated and its value is returned.
