How to x in python?

Python Arithmetic operators are used to perform basic mathematical operations like addition, subtraction, multiplication, and division.

In Python 3.x the result of division is a floating-point while in Python 2.x division of 2 integers was an integer. To obtain an integer result in Python 3.x floored (// integer) is used.

Division Operators allow you to divide two numbers and return a quotient, i.e., the first number or number at the left is divided by the second number or number at the right and returns the quotient.

There are two types of division operators:

The quotient returned by this operator is always a float number, no matter if two numbers are integers. For example:

Output:

The quotient returned by this operator is dependent on the argument being passed. If any of the numbers is float, it returns output in float. It is also known as Floor division because, if any number is negative, then the output will be floored. For example:

Output:

The precedence of Arithmetic Operators in python is as follows:

The modulus operator helps us extract the last digit/s of a number. For example:

Here is an example showing how different Arithmetic Operators in Python work:

Output:

In Python Comparison of Relational operators compares the values. It either returns True or False according to the condition.

= is an assignment operator and == comparison operator.

In python, the comparison operators have lower precedence than the arithmetic operators. All the operators within comparison operators have same precedence order.

Let’s see an example of Comparison Operators in Python.

Python Logical operators perform Logical AND, Logical OR, and Logical NOT operations. It is used to combine conditional statements.

The precedence of Logical Operators in python is as follows:

The following code shows how to implement Logical Operators in Python:

Python Bitwise operators act on bits and perform bit-by-bit operations. These are used to operate on binary numbers.

The precedence of Bitwise Operators in python is as follows:

Here is an example showing how Bitwise Operators in Python work:

Python Assignment operators are used to assign values to the variables.

Let’s see an example of Assignment Operators in Python.

In Python, is and is not are the identity operators both are used to check if two values are located on the same part of the memory. Two variables that are equal do not imply that they are identical.

Let’s see an example of Identity Operators in Python.

In Python, in and not in are the membership operators that are used to test whether a value or variable is in a sequence.

The following code shows how to implement Membership Operators in Python:

in Python, Ternary operators also known as conditional expressions are operators that evaluate something based on a condition being true or false. It was added to Python in version 2.5.

It simply allows testing a condition in a single line replacing the multiline if-else making the code compact.

Here is a simple example of Ternary Operator in Python.

Output:

In Python, Operator precedence and associativity determine the priorities of the operator.

This is used in an expression with more than one operator with different precedence to determine which operation to perform first.

Let’s see an example of how Operator Precedence in Python works:

If an expression contains two or more operators with the same precedence then Operator Associativity is used to determine. It can either be Left to Right or from Right to Left.

The following code shows how Operator Associativity in Python works:

To try your knowledge of Python Operators, you can take out the quiz on Python Operators.

Operators are used to perform operations on variables and values.

In the example below, we use the + operator to add together two values:

Python divides the operators in the following groups:

Arithmetic operators are used with numeric values to perform common mathematical operations:

Assignment operators are used to assign values to variables:

Comparison operators are used to compare two values:

Logical operators are used to combine conditional statements:

Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:

Membership operators are used to test if a sequence is presented in an object:

Bitwise operators are used to compare (binary) numbers:

Operator precedence describes the order in which operations are performed.

The precedence order is described in the table below, starting with the highest precedence at the top:

If two operators have the same precedence, the expression is evaluated from left to right.
