Python is a user-friendly programming language that makes your life easy. That’s one of the reasons it is the most preferable language to most developers. Besides its simple syntax and useful built-in methods, Python is famous for its variety of operators, such as +,=,-,% and * that you can use for doing calculations quickly. As there are many operators in Python that you can use within programs, this article will help you know more about them. Read on…

What are Operators in Python?

In Python, you are able to perform various operations on variables using operators. They can be considered as special symbols that are used for specifying that some computation has to be executed. These computations may be arithmetic or logical. For example,

>>> 2+2

4

Here, the + symbol is the arithmetic operator performing the addition of two numbers, 2 and 2. The numbers, 2 and 2, are the operands and 4 is the final output. An operator can be a literal value, such as 2 or a variable. For example,

>>> a= 4

>>> b= 8

>>> a+b

12  

Such a sequence of operators in Python along with the operands are together called an expression.

Let us now look at the different operators in Python!

Types of Python Operators

Arithmetic operators

These operators are used for performing basic mathematical operations in Python. And, they are:

• Addition

It adds two or more operands, such as 2+5 is 7 

• Subtraction

It subtracts one operand from the other like  2-5 is -3

• Multiplication

It multiplies two operands like 2*5 is 10

• Division

It divides two operands, such as 4/2 is 2

• Exponentiation

This raises the first number to the power of the second number like 2**2 is 4

• Floor division

This divides two operands and gives the quotient, such as 10//3 is 3

• Modulus

This divides two operands and gives the remainder value like  10%3 is 1

Relational operators

These operators in Python are used for comparing two values and return the output as True or False.

• >

It checks whether the left operand is larger than the right, and returns True or False. Example: 4>3 (True)

• <

It checks whether the left operand is smaller than the right, and returns True or False. Example: 4<3 (False)

• ==

It checks whether two operands are equal, and returns True or False. Example: 4==3 (False)

• !=

It checks whether two operands are not equal, and returns True or False.

• >=

It evaluates whether x is greater than or equal to y, and returns True or False.

• <=

It returns True if x is less than or equal to y.

Logical operators

You can use them for combining two logical statements. 

• And

This returns True if two statements are correct.

• Or

This returns True if one of the statements is correct.

• Not

This reverses the output and returns False if the output is True.

Bitwise operators

They are used for comparing binary numbers.

• & (AND) – When both bits are 1, it sets each bit to 1.
• | (OR) – When one of the two bits is 1, this operator in Python sets each of them to 1.
• ^ (XOR) – When one of the two bits is 1, it sets each bit to 1.
• ~  (NOT) – This operator inverts the bit values.
• << – This shifts bits of a number to the left as per the specified number of places.
• >> – This shifts bits of a number to the right as per the specified number of places.

Assignment operators

Variables are assigned values using these operators.

Identity operators

These operators in Python are used for determining whether two variables are located in the same memory location.

• is 

This operator returns True if two operands are equal, referring to the same object. For example, >>> ‘4’ is “4” (True)

• is not  

This returns True when two numbers are not equal. This means they do not refer to the same object. For example, >>> ‘4’ is “40” (False)

Membership operators

These operators in Python are used for evaluating whether a variable exists in a sequence or not.

• in 

It checks if a value is part of a sequence, such as a list. For example, >> ‘cat’ in ‘categories’ (True)

• not in 

It checks if a value is not a part of a sequence. For example, >> ‘cat’ in ‘Batman’ (False)

Examples  of Arithmetic Operators in Python:

Python, as a versatile programming language, offers a wide range of operators that allow developers to perform various operations on data. Whether it’s arithmetic calculations or logical evaluations, understanding the various types of operators in Python is essential for writing efficient and expressive code. 

In Python, arithmetic operators are utilized to carry out fundamental mathematical calculations. These operators enable us to add, subtract, multiply, divide, and perform other mathematical operations on numerical values. The following are the regularly used arithmetic operators in Python:

1. Addition (+)

The addition operator is denoted by a plus sign (+) and is used to add two values together. For example, 3 + 5 will yield the result 8.

             x = 5
             y = 3
            result = x + y
           print(result) # Output: 8

2. Subtraction (-)

The subtraction operator is denoted by a minus sign (-) and is used to subtract one value from another. For example, 10 – 7 will yield the result 3.

            x = 10
            y = 7
           result = x - y
           print(result) # Output: 3

3. Multiplication ()

The multiplication operator is denoted by an asterisk () and is used to multiply two values. For example, 4 * 6 will yield the result 24.

            x = 4
            y = 6
            result = x * y
            print(result) # Output: 24

4. Division (/)

The division operator is denoted by a forward slash (/) and is used to divide one value by another. For example, 10 / 2 will yield the result 5. Note that division in Python 3 returns a floating-point result.

            x = 10
            y = 2
         result = x / y
         print(result) # Output: 5.0

5. Modulo (%)

The modulo operator is denoted by a per cent sign (%) and is used to find the remainder after division. For example, 10 % 3 will yield the result 1, as 10 divided by 3 leaves a remainder of 1.

            x = 10
            y = 3
            result = x % y
            print(result) # Output: 1

6. Exponentiation ()

The exponentiation operator is denoted by two asterisks () and is used to raise a value to the power of another value. For example, 2 ** 3 will yield the result 8, as 2 raised to the power of 3 is 8.

            x = 2
            y = 3
            result = x ** y
            print(result) # Output: 8

Examples of Logical Operators in Python

Python has three logical operators which are used to work with Boolean values- True or False. These operators are commonly used in conditional statements, and they control flow structures.

1. The AND operator will result in a True value only when both the operands given to it are True. In the case of True and False, it will give a False output.
2. OR (or): The OR operator returns True if one of the operands is True; or else, it returns False. For example, True or False will yield True.
3. NOT (not): The NOT operator returns the opposite of the operand. If the operand is True, it returns False, and if the operand is False, it returns True. For example, not True will yield False.
