OVERVIEW
In this blog, you will learn all about the different types of operators in python. Which are:
- Arithmetic Operators
- Comparison(Relational) Operators
- Membership Operators
- Logical Operators
- Bitwise Operators
- Identity Operators
- Assignment operators
Now let’s understand about them one by one.
ARITHMETIC OPERATORS IN PYTHON
| Operator | Description | Example |
| + Addition | This will add all the values used with this operator. | =>a+b =>4+5 =>9 |
| – Subtraction | This will subtract the right side value from the left side value used with this operator. | =>a-b =>8-5 =>3 |
| * Multiplication | This will multiply all the values used with this operator. | =>a*b =>8*5 =>40 |
| / Division | This will divide the left value with the right value with this operator. | =>a/b =>8/5 =>1.6 |
| % Modulus | This will divide the left value with the right value and will return the reminder. | =>a%b =>8%5 =>3 |
| // Floor division | Floor Division – The division of operands where the result is the quotient in which the digits after the decimal point are removed. | 9//2 = 4 and 9//2.0 = 4.0 |
| ** Exponent | This will perform the exponential calculation on the operators. | =>4**3 =>64 |
Example
Assume variable a holds 10 and variable b holds 20, then-
When you execute the above program arithmetic operators in python, it returns the following result-
COMPARISON OPERATORS IN PYTHON
| Operator | Description | Example |
| == | If both values around the operand are equal, it will return True otherwise it will return False | =>(a==b) => (10==20) =>False |
| != | If both values around the operand are not equal, it will return True otherwise it will return False | =>(a!=b) => (10!=20) =>True |
| < | If the left value is less than the right value, it will return True otherwise it will return False | =>(a<b) => (10<20) =>True |
| > | If the left value is greater than the right value, it will return True otherwise it will return False | =>(a>b) => (10>20) =>False |
| <= | If the left value is less than or equal to the right value, it will return True otherwise it will return False | =>(a<=b) => (20<=20) =>True |
| >= | If the left value is greater than or equal to the right value, it will return True otherwise it will return False | =>(a>=b) => (30>=20) =>True |
Example
Assume variable a holds 10 & variable b holds 20, then-
When you execute the above program comparison operators in python, it returns the following result-
ASSIGNMENT OPERATORS IN PYTHON
| Operator | Description | Example |
| = | Assigns values from right side operands to left side operand | c=a+b value(a+b) is assigned to c |
| += | It will add the right value to the left value and will assign the result to the left operand. | c+=a is equivalent to the c=c+a |
| -= | It will subtract the right value from the left value and will assign the result to the left operand. | c-=a is equivalent to the c=c-a |
| *= | It will multiply the right value to the left value and will assign the result to the left operand. | c*=a is equivalent to the c=c*a |
| /= | It will divide the right value from the left value and will assign the result to the left operand. | c/=a is equivalent to the c=c/a |
| %= | It will divide the right value from the left value and the remainder value will assign the result to the left operand. | c%=a is equivalent to the c=c%a |
| **= | It will perform exponential(power) calculation and will assign the result to the left operand. | c**=a is equivalent to the c=c**a |
| //= | It performs floor division on operators and assign value to the left operand. | c//=a is equivalent to the c=c//a |
Example
Assume variable a holds 10 and variable b holds 20, then-
When you execute the above program assignment operators in python, it returns the following result-
BITWISE OPERATORS IN PYTHON
Bitwise operators works bit wise and performs operation bit-by-bit. Assume a = 60 and b = 13. Now in binary format they will be as follows-
a = 0011 1100
b = 0000 1101
———————-
a&b = 0000 1100
a|b = 0011 1101
a^b = 0011 0001
~a = 1100 0011
Python’s built-in function bin() can be used to obtain binary representation of an integer
number.
| Operator | Description | Example |
| & | Operator copies a bit to the result, if it exists in both operands | =>(a & b) =>(0011 1100 & 0000 1101) =>0000 1100 |
| | | It copies a bit, if it exists in either operand. | =>(a | b) => (0011 1100 | 0000 1101) => 61 (means 0011 1101) |
| ^ | It copies the bit, if it is set in one operand but not both. | =>(a ^ b) => (0011 1100 ^ 0000 1101) => 49 (means 0011 0001) |
| ~ | It is unary and has the effect of ‘flipping’ bits. | =>(~a ) => ~(0011 1100) => -61 (means 1100 0011 in 2’s complement form due to a signed binary number. |
| << | The left operand’s value is moved left by the number of bits specified by the right operand. | a << = 240 (means 1111 0000) |
| >> | The left operand’s value is moved right by the number of bits specified by the right operand. | a >> = 15 (means 0000 1111) |
Example
When you execute the above program bitwise operators in python, it returns the following result-
LOGICAL OPERATORS IN PYTHON
The following logical operators in python are supported by Python language. Assume variable a has value True and variable b has value False then-
| Operator | Description | Example |
| and | If both side of the operator the value is true that it returns True, otherwise False | =>(a and b) =>False. |
| or | If either side of the operator the value is true that it returns True, otherwise False | =>(a or b) =>True. |
| not | Used to invert the logical state of its operand. | =>not(a and b) =>True. |
MEMBERSHIP OPERATORS IN PYTHON
| Operator | Description | Example |
| in | It evaluates the output to true, if it finds a variable in the specified sequence, otherwise false. | =>6 in [1,2,3,4,5,6] =>True |
| not in | It evaluates the output to true, if it doesn’t find a variable in the specified sequence, otherwise false. | =>6 not in [1,2,3,4,5,6] =>False |
Example
When you execute the above program for membership operators in python, it returns the following result-
IDENTITY OPERATORS IN PYTHON
| Operator | Description | Example |
| is | It evaluates to true if the variables on either side of the operator point to the same object and false otherwise. | x is y, here is results in 1 if id(x) equals id(y). |
| is not | It evaluates to false if the variables on either side of the operator point to the same object and false otherwise. | x is not y, here is not results in 1 if id(x) is not equal to id(y). |
Example
When you execute the above program identity operators in python, it returns the following result-
