Python Assignment Operators

The Python Assignment Operators are used to assign the values to the declared variables. Equals (=) operator is the most commonly used assignment operator in Python. For example:

i = 10

Below table displays the list of  available assignment operators in Python language.

Python Assignment Operators Example

For this example, We are using four variables a, Total, x, y and their values are 7, 21, 9 and 65. We are going to use these four variables to show you the working functionality of all the Python Assignment Operators with example

PYTHON CODE

# Program to show all Python Assignment Operators */

>>> a = 7
>>> Total = 21
>>> Total += a # Using += Operator
>>> print("The Value of the Total after using += Operator is: ", Total)
>>> Total -= a # Using -= Operator
>>> print("The Value of the Total after using -= Operator is: ", Total)
>>> Total *= a # Using *= Operator
>>> print("The Value of the Total after using *= Operator is: ", Total)
>>> Total //= a # Using //= Operator
>>> print("The Value of the Total after using //= Operator is: ", Total)
>>> Total **= a # Using **= Operator
>>> print("The Value of the Total after using **= Operator is: ", Total)
>>> Total /= a # Using /= Operator
>>> print("The Value of the Total after using /= Operator is: ", Total)
>>> Total %= a # Using %= Operator
>>> print("The Value of the Total after using %= Operator is: ", Total)
>>> x = 9
>>> y = 65
>>> x &= y # Using &= Operator
>>> print("The Value of the x after using &= Operator is: ", x)
>>> x |= 9 # Using |= Operator
>>> print("The Value of the x after using |= Operator is: ", x)
>>> x ^= y # Using ^= Operator
>>> print("The Value of the x after using ^= Operator is: ", x)

OUTPUT

ANALYSIS

In this Python Assignment Operators example program, We declared 2 integer values a, Total and we assigned values 7 and 21 respectively.

 a = 7
 Total = 21

Below print statements will display the output of the Total after using Python Assignment Operators on a and Total

Let us see the functionalities of all the Python Assignment Operators

First assignment operator functionality,

 Total += a # Using += Operator
 print("The Value of the Total after using += Operator is: ", Total)

Total += a means

Total = Total + a ⇒ 21 + 7 = 28

So, the output of the above mentioned print statement will be 28

The functionality of a Second assignment operator in Python,

 Total -= a # Using -= Operator
 print("The Value of the Total after using -= Operator is: ", Total)

Total -= a means

Total = Total – a ⇒ 28 – 7 = 21

So, the output of the above mentioned print statement will be 21

Third assignment operator functionality,

 Total *= a # Using *= Operator
 print("The Value of the Total after using *= Operator is: ", Total)

Total *= a means

Total = Total * a ⇒ 21 * 7 = 147

So, the output of the above mentioned print statement will be 147

Fourth assignment operator functionality,

 Total //= a # Using //= Operator
 print("The Value of the Total after using //= Operator is: ", Total)

Total //= a means

Total = Total // a ⇒ 147 // 7 = 21

So, the output of the above mentioned print statement will be 21

Fifth assignment operator functionality,

 Total **= a # Using **= Operator
 print("The Value of the Total after using **= Operator is: ", Total)

Total **= a means

Total = Total ** a ⇒ 21*21*21 *21*21*21*21 = 1,801,088,541

So, the output of the above mentioned print statement will be 1,801,088,541

Sixth assignment operator functionality,

Total /= a # Using /= Operator
>>> print("The Value of the Total after using /= Operator is: ", Total)

Total /= a means

Total = Total / a ⇒ 1,801,088,541 / 7 = 257,298,363

So, the output of the above mentioned print statement will be 257,298,363

The functionality of a Seventh assignment operator in python is

 Total %= a # Using %= Operator
 print("The Value of the Total after using %= Operator is: ", Total)

Total %= a means

Total = Total % a ⇒257,298,363 % 7 = 0 (because Remainder of 257,298,363 /7 is = 0)

In the next line, We declared 2 integer values x, y and we assigned values 9 and 65 respectively.

 x = 9
 y = 65

Eighth assignment operator functionality,

 x &= y # Using &= Operator
 print("The Value of the x after using &= Operator is: ", x)

x &= y means

x = x & y ⇒ 9 & 65

⇒ 00001001 & 01000001 = 00000001 ⇒ 1

So, the output of the above mentioned print statement will be 1. Please refer Python Bitwise Operators for better understanding

Ninth assignment operator functionality,

 x |= 9 # Using |= Operator
 print("The Value of the x after using |= Operator is: ", x)

x |= y means

x = x | y ⇒ 1 | 9

⇒ 00000001 | 00001001 = 00001001 ⇒ 9

So, the output of the above mentioned print statement will be 9

The functionality of a Tenth assignment operator in Python,

x ^= y # Using ^= Operator
>>> print("The Value of the x after using ^= Operator is: ", x)

x ^= y means

x = x ^ y ⇒ 9 ^65

⇒ 00001001 ^ 01000001 = 01001000 ⇒ 72

So, the output of the above mentioned print statement will be 72
