In this **python tutorial**, you will learn **how to Swap Two Number using arithmetic operators** and print function of the python programming language.

## How to Swap Two Numbers in Python?

Let’s take a look at the first source code , here the integer values are assigned in the code and the arithmetic operator = carries out the function.

RUN CODE SNIPPET# Python code to swap two numbers x = 45 y = 70 print ("Before swapping: ") print("Value of x : ", x, " and y : ", y) # code to swap 'x' and 'y' x, y = y, x print ("After swapping: ") print("Value of x : ", x, " and y : ", y)

**OUTPUT:**

Before swapping: Value of x : 45 and y : 70 After swapping: Value of x : 70 and y : 45

- At the start, we declare the variables
`x`

and`y`

with the integer values`45`

and`70`

. - We display the Statements
`"Before Swapping: "`

followed by the statement`("Value of x : ", x, " and y : ", y)`

which holds the declared variables after the comma. It is displayed using the`print`

function. - The swap code here uses the equals operator =, which has a built function that swaps the input integers and displays the output, the code goes as
`x, y = y, x`

- We display the Statements
`"After Swapping: "`

after the swap code, followed by the statement`("Value of x : ", x, " and y : ", y)`

which holds the declared variables after the comma. It is displayed using the`print`

function.

Let’s take a look at the second source code, here the integer values are assigned in the code and the arithmetic operator + and – carries out the function.

RUN CODE SNIPPET# Python code to swap two numbers using + and - operators x = 12.7 y = 4.3 print ("Before swapping: ") print("Value of x : ", x, " and y : ", y) # Swap code x = x + y # x = 17.0, y = 4.3 y = x - y # x = 17.0, y = 12.7 x = x - y # x = 4.3, y = 12.7 print ("After swapping: ") print("Value of x : ", x, " and y : ", y)

**OUTPUT:**

Before swapping: Value of x : 12.7 and y : 4.3 After swapping: Value of x : 4.3 and y : 12.7

- At the start, we declare the variables
`x`

and`y`

with the integer values`12.7`

and`4.3`

. - We display the Statements
`"Before Swapping: "`

followed by the statement`("Value of x : ", x, " and y : ", y)`

which holds the declared variables after the comma. It is displayed using the`print`

function. - The swap code here uses the addition and subtraction operators (+ and -), which has a built function that swaps the input integers and displays the output, the code goes as
`x = x + y`

,`y = x - y`

and`x = x - y`

respectively one below the other. - We display the Statements
`"After Swapping: "`

after the swap code, followed by the statement`("Value of x : ", x, " and y : ", y)`

which holds the declared variables after the comma. It is displayed using the`print`

function.

Let’s take a look at the third source code, here the integer values are assigned in the code and the arithmetic operator * and / carries out the function.

RUN CODE SNIPPET# Python code to swap two numbers using / and * operators x = 12.7 y = 4.3 print ("Before swapping: ") print("Value of x : ", x, " and y : ", y) # Swap code x = x * y # x = 54.61, y = 4.3 y = x / y # x = 54.61, y = 12.7 x = x / y # x = 4.3, y = 12.7 print ("After swapping: ") print("Value of x : ", x, " and y : ", y)

**OUTPUT:**

Before swapping: Value of x : 12.7 and y : 4.3 After swapping: Value of x : 4.3 and y : 12.7

- At the start, we declare the variables
`x`

and`y`

with the integer values`12.7`

and`4.3`

. - We display the Statements
`"Before Swapping: "`

followed by the statement`("Value of x : ", x, " and y : ", y)`

which holds the declared variables after the comma. It is displayed using the`print`

function. - The swap code here uses the multiplication and division operators (* and /), which has a built function that swaps the input integers and displays the output, the code goes as
`x = x * y`

,`y = x / y`

and`x = x / y`

respectively one below the other. - We display the Statements
`"After Swapping: "`

after the swap code, followed by the statement`("Value of x : ", x, " and y : ", y)`

which holds the declared variables after the comma. It is displayed using the`print`

function.

**NOTE:**

- The
**equals**operator is the simple built – in method which is easy to use. - The
**addition**and**subtraction**method of swapping numbers is used for variables which are assigned numerical values and not strings values or any other. - The
**multiplication**and**division**method of swapping number is used for variables which are assigned numerical values other than zero. - The
**print**statement/string to be displayed in enclosed in double quotes. - The
**integers**are zero, positive or negative whole numbers without a fractional part.
