# Python 3 - Assignment Operators Example

Assume variable a holds the value 10 and variable b holds the value 20, then −

Operator Description Example
= Assigns values from right side operands to left side operand c = a + b assigns value of a + b into c
+= Add AND It adds right operand to the left operand and assign the result to left operand c += a is equivalent to c = c + a
-= Subtract AND It subtracts right operand from the left operand and assign the result to left operand c -= a is equivalent to c = c - a
*= Multiply AND It multiplies right operand with the left operand and assign the result to left operand c *= a is equivalent to c = c * a
/= Divide AND It divides left operand with the right operand and assign the result to left operand c /= a is equivalent to c = c / ac /= a is equivalent to c = c / a
%= Modulus AND It takes modulus using two operands and assign the result to left operand c %= a is equivalent to c = c % a
**= Exponent AND Performs exponential (power) calculation on operators and assign value to the left operand c **= a is equivalent to c = c ** a
//= Floor Division It performs floor division on operators and assign value to the left operand c //= a is equivalent to c = c // a

## Example

Assume variable a holds the value 10 and variable b holds the value 20, then −

```#!/usr/bin/python3

a = 21
b = 10
c = 0

c = a + b
print ("Line 1 - Value of c is ", c)

c += a
print ("Line 2 - Value of c is ", c )

c *= a
print ("Line 3 - Value of c is ", c )

c /= a
print ("Line 4 - Value of c is ", c )

c  = 2
c %= a
print ("Line 5 - Value of c is ", c)

c **= a
print ("Line 6 - Value of c is ", c)

c //= a
print ("Line 7 - Value of c is ", c)

```

## Output

When you execute the above program, it produces the following result −

```Line 1 - Value of c is  31
Line 2 - Value of c is  52
Line 3 - Value of c is  1092
Line 4 - Value of c is  52.0
Line 5 - Value of c is  2
Line 6 - Value of c is  2097152
Line 7 - Value of c is  99864
