Python Arithmetic Operators

The Python operators are fundamental for performing mathematical calculations in programming languages like Python, Java, C++, and many others. Arithmetic operators are symbols used to perform mathematical operations on numerical values. In most programming languages, arithmetic operators include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%).

Arithmetic Operators in Python

There are 7 arithmetic operators in Python. The lists are given below:

Precedence of Arithmetic Operators in Python

Let us see the precedence and associativity of Python Arithmetic operators.

Addition Operator

In Python, + is the addition operator. It is used to add 2 values.

val1 = 2
val2 = 3

# using the addition operator
res = val1 + val2
print(res)

Output: 

5

Subtraction Operator

In Python, – is the subtraction operator. It is used to subtract the second value from the first value.

val1 = 2
val2 = 3

# using the subtraction operator
res = val1 - val2
print(res)

Output:

-1

Multiplication Operator

Python * operator is the multiplication operator. It is used to find the product of 2 values.

val1 = 2
val2 = 3

# using the multiplication operator
res = val1 * val2
print(res)

Output : 

6

Division Operator 

Python // operator is the division operator. It is used to find the quotient when the first operand is divided by the second.

val1 = 3
val2 = 2

# using the division operator
res = val1 / val2
print(res)

Output:

1.5

Floor Division Operator

The // in Python is used to conduct the floor division. It is used to find the floor of the quotient when the first operand is divided by the second.

val1 = 3
val2 = 2

# using the floor division
res = val1 // val2
print(res)

Output:

1

Modulus Operator

The % in Python is the modulus operator. It is used to find the remainder when the first operand is divided by the second. 

val1 = 3
val2 = 2

# using the modulus operator
res = val1 % val2
print(res)

Output:

1

Exponentiation Operator

In Python, ** is the exponentiation operator. It is used to raise the first operand to the power of the second. 

val1 = 2
val2 = 3

# using the exponentiation operator
res = val1 ** val2
print(res)

Output:

8

Python Arithmetic Operators – FAQs

What are the 7 arithmetic operators in Python?

Python has seven basic arithmetic operators used to perform mathematical operations:

1. Addition (+): Adds two numbers.

result = 3 + 2  # Output: 5

1. Subtraction (-): Subtracts one number from another.

result = 5 - 2  # Output: 3

1. Multiplication (*): Multiplies two numbers.

result = 3 * 2  # Output: 6

1. Division (/): Divides one number by another, returning a float.

result = 6 / 2  # Output: 3.0

1. Floor Division (//): Divides one number by another, returning an integer.

result = 7 // 2  # Output: 3

1. Modulus (%): Returns the remainder of a division.

result = 7 % 2  # Output: 1

1. Exponentiation (**): Raises one number to the power of another.

result = 3 ** 2  # Output: 9

What are the 6 relational operators in Python?

Python has six relational operators used to compare values:

1. Equal to (==): Checks if two values are equal.
2. Not equal to (!=): Checks if two values are not equal.
3. Greater than (>): Checks if the left value is greater than the right value.
4. Less than (<): Checks if the left value is less than the right value.
5. Greater than or equal to (>=): Checks if the left value is greater than or equal to the right value.
6. Less than or equal to (<=): Checks if the left value is less than or equal to the right value.

What is the rule for arithmetic operators in Python?

Arithmetic operators in Python follow the standard mathematical order of operations, also known as BODMAS/BIDMAS rules:

1. Brackets
2. Orders (exponentiation, **)
3. Division and Multiplication (/, *, //, %)
4. Addition and Subtraction (+, -)

result = 3 + 2 * 2 ** 2 / 2 - 1  # Output: 6.0
# Explanation: 3 + ((2 * (2 ** 2)) / 2) - 1
#              3 + ((2 * 4) / 2) - 1
#              3 + (8 / 2) - 1
#              3 + 4 - 1
#              7 - 1
#              6.0

What is the === in Python?

Python does not have a === operator. In many other programming languages like JavaScript, === is a strict equality operator that checks both the value and the type. In Python, you use == to check for equality and is to check for identity (if two references point to the same object).

What is the arithmetic operator?

An arithmetic operator is a symbol that performs a mathematical operation on one or more operands. The basic arithmetic operators in Python include addition (+), subtraction (-), multiplication (*), division (/), floor division (//), modulus (%), and exponentiation (**). These operators are used to perform calculations and return a numeric result.
