12.2.3 Assignment Operators
Assignment operators are used to assign values to variables. Python also provides compound assignment operators,
which combine an arithmetic operation with assignment. These operators allow you to update the value of a variable
more efficiently, without having to write the variable name twice.
The following table shows the Assignment operators in Python along with their description:

Operator Description
= Assign the value of the right operand to the left operand.
+= Adds right operand to left operand and assigns the result to left operand.
-= Subtracts right operand from left operand and assigns the result to left operand.
*= Multiplies left operand by right operand and assigns the result to left operand.
/= Divides left operand by right operand and assigns the result to left operand.
%= Takes the reminder after division and assigns it to the left operand.

# To assign value 15 to variable x
x = 15
print("Initial value of x:", x)

# To add 5 to x using += operator
x += 5
print("After x += 5:", x)

# To subtract 3 from x using -= operator
x -= 3
print("After x -= 3:", x)

# To multiply x by 2 using *= operator
x *= 2
print("After x *= 2:", x)

# To divide x by 4 using /= operator
x /= 4
print("After x /= 4:", x)

# To find remainder of x divided by 3 using %= operator
x %= 3
print("After x %= 3:", x)

# To perform floor division of x by 2 using //= operator
x //= 2
print("After x //= 2:", x)

# To raise x to the power of 3 using **= operator
x **= 3
print("After x **= 3:", x)
