Listing 4-7 while statement with a Status Variable

The assignment expression (alias walrus expression) was introduced in Python 3.8, and it provides an elegant solution to the issue shown earlier. In Listing 4-8 the assignment of the level of discount located in the expression guards the while loop. The code will be more transparent; therefore, the same value giving the statement will not have to be repeated in two places or have not have to introduce a new variable to delay the evaluation of the condition.product = Product('K01', 'cube', 1000)

while not 0 < (discount_value

:= int(input('Amount of the discount (in %)?'))) <= 99:

print('Discount abount is too low or too high')

product.reduce_price(discount_value)
