Assignment Operators in Python

Assignment Operators

These operators are useful when assigning values to variables:

Operators         Function

=	assigns the value of the right operand to the left operand
	adds the value of the right and left operand and assigns the
+= add and	total to the left operand
-= subtract	deducts the value of the right operand from the value of the
and	left operand and assigns the new value to the left operand
*= multiply	multiplies the left and right operand and assigns the product
and	to the left operand
/= divide	divides the left operand with the value of the right operand
and	and assigns the quotient to the left operand
**=	performs exponential operation on the left operand and
exponent	assigns the result to the left operand
//= floor	performs floor division on the left operand and assigns the
division and	result to the left operand

= Operator

You have seen this operator at work in previous chapters when you have assigned different values to variables. Examples:

a = c

a = b + c

a = 8

a = 8 + 6

s = “I love Python.”

+= add and

The ‘add and’ (+=) operator is simply another way to express x = x + a so that you’ll end up with the statement x += a.

-= subtract and

The ‘subtract and’ (-=) operator is equivalent to the expression x = x – a and is expressed with the statement x-=a

*= multiply and

The ‘multiply and’ (*=) operator is the equivalent of the statement x = x * a and is expressed with x*=a.

/= divide and

The ‘divide and’ (/=) operator is like saying x = x/a and is expressed with the statement x/=a.

%= modulus and

The ‘modulus and’ (%=) operator is another way to say x = x % a where you’ll end up instead with the expression x%=a.

//= floor division and

The ‘floor division and’ is equivalent to the expression x = x//a and takes the form x//=a.
