Like other programming languages, Python Operators are essential building blocks, and Python is no exception. Operators are the backbone of Python expressions. They allow you to perform operations on variables and values, enabling everything from basic math to complex decision-making and data manipulation.
In this blog post, we’ll explore all the major operator groups in Python, with clear examples to solidify your understanding.
1. Arithmetic Operators
Python provides a set of arithmetic operators to perform common mathematical operations such as addition, subtraction, multiplication, and division. These operators can be used with integers, variables, and expressions.
Operator | Description | Example | Result |
---|---|---|---|
+ | Addition | 10 + 5 |
15 |
– | Subtraction | 10 - 5 |
5 |
* | Multiplication | 10 * 5 |
50 |
/ | Division | 10 / 5 |
2.0 |
// | Floor Division | 10 // 3 |
3 |
% | Modulus | 10 % 3 |
1 |
** | Exponentiation | 2 ** 3 |
8 |
1 2 3 4 5 6 7 8 9 |
a = 10 b = 5 print ("a + b : ", a + b) # Addition print ("a - b : ", a - b) # Subtraction print ("a * b : ", a * b) # Multiplication print ("a / b : ", a / b) # Division print ("a % b : ", a % b) # Modulus print ("a ** b : ", a ** b) # Exponent print ("a // b : ", a // b) # Floor Division |
2. Assignment Operators
In Python, assignment operators are used to assign values to variables. The most fundamental assignment operator is the single equals sign (=
), which assigns the value on the right-hand side of the operator to the variable on the left-hand side.
Operator | Usage | Equivalent |
---|---|---|
= | x = 5 |
Assigns 5 to x |
+= | x += 3 |
x = x + 3 |
-= | x -= 2 |
x = x - 2 |
*= | x *= 4 |
x = x * 4 |
/= | x /= 2 |
x = x / 2 |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
# Assignment Operator a = 10 # Addition Assignment a += 5 print ("a += 5 : ", a) # Subtraction Assignment a -= 5 print ("a -= 5 : ", a) # Multiplication Assignment a *= 5 print ("a *= 5 : ", a) # Division Assignment a /= 5 print ("a /= 5 : ",a) # Remainder Assignment a %= 3 print ("a %= 3 : ", a) # Exponent Assignment a **= 2 print ("a **= 2 : ", a) # Floor Division Assignment a //= 3 print ("a //= 3 : ", a) |
3. Comparison Operators
Python uses comparison operators to compare two values. These operators evaluate the relationship between the values and return a Boolean result — either True
or False
— based on the outcome of the comparison.
Operator | Description | Example | Result |
---|---|---|---|
== | Equal to | 5 == 5 |
True |
!= | Not equal to | 5 != 3 |
True |
> | Greater than | 5 > 3 |
True |
< | Less than | 5 < 10 |
True |
>= | Greater than or equal to | 5 >= 5 |
True |
<= | Less than or equal to | 5 <= 6 |
True |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
a = 4 b = 5 # Equal print ("a == b : ", a == b) # Not Equal print ("a != b : ", a != b) # Greater Than print ("a > b : ", a > b) # Less Than print ("a < b : ", a < b) # Greater Than or Equal to print ("a >= b : ", a >= b) # Less Than or Equal to print ("a <= b : ", a <= b) |
4. Logical Operators
Python logical operators are utilized to construct Boolean expressions and determine their truth values. They are essential for formulating conditional statements and controlling the program’s execution flow. Python provides three fundamental logical operators: and, or, and not.
Operator | Description | Example | Result |
---|---|---|---|
and | Both conditions true | True and False |
False |
or | At least one condition is true | True or False |
True |
not | Inverts Boolean result | not True |
False |
1 2 3 4 |
x = 5 y = 10 if x > 3 and y < 15: print("Both x and y are within the specified range") |
5. Identity Operators
Python identity operators are used to compare the memory addresses of two objects rather than their values. If both objects reference the same memory location, the comparison evaluates to True; otherwise, it evaluates to False. Python provides two identity operators: is and is not.
Operator | Description | Example | Result |
---|---|---|---|
is | Same object | a is b |
True/False |
is not | Not the same object | a is not c |
True/False |
1 2 3 4 5 6 |
x = 10 y = 5 if x is y: print("x and y are the same object") else: print("x and y are not the same object") |
6. Membership Operators
Python membership operators are employed to ascertain whether a specific value exists within a sequence. They facilitate the verification of element membership across various Python data structures, including lists, tuples, sets, and strings. Python provides two primary membership operators: in and not in.
Operator | Description | Example | Result |
---|---|---|---|
in | Value exists in sequence | 'a' in 'apple' |
True |
not in | Value does not exist | 3 not in [1, 2] |
True |
1 2 3 4 5 |
fruits = ["apple", "banana", "cherry"] if "banana" in fruits: print("Yes, banana is a fruit!") else: print("No, banana is not a fruit!") |
7. Bitwise Operators
Python bitwise operators perform operations on the individual bits of binary integers. They operate on the binary representations of integers, applying logical operations to each bit position. Python includes several bitwise operators, such as AND (&
), OR (|
), NOT (~
), XOR (^
), left shift (<<
), and right shift (>>
).
Operator | Description | Example | Result |
---|---|---|---|
& | AND | 5 & 3 |
1 |
| | OR | 5 | 3 |
7 |
^ | XOR | 5 ^ 3 |
6 |
~ | NOT | ~5 |
-6 |
<< | Left Shift | 5 << 1 |
10 |
>> | Right Shift | 5 >> 1 |
2 |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
a = 60 # 60 = 0011 1100 b = 13 # 13 = 0000 1101 # Binary AND c = a & b # 12 = 0000 1100 print ("a & b : ", c) # Binary OR c = a | b # 61 = 0011 1101 print ("a | b : ", c) # Binary XOR c = a ^ b # 49 = 0011 0001 print ("a ^ b : ", c) # Binary Ones Complement c = ~a; # -61 = 1100 0011 print ("~a : ", c) # Binary Left Shift c = a << 2; # 240 = 1111 0000 print ("a << 2 : ", c) # Binary Right Shift c = a >> 2; # 15 = 0000 1111 print ("a >> 2 : ", c) |
