Incrementing and Decrementing
Look at the table to understand how to minimize the writing of mathematical operators!
| Formula | How to minimize |
|---|---|
a = a + 1 | a += 1 |
a = a - 1 | a -= 1 |
a = a * 2 | a *= 2 |
a = a / 2 | a /= 2 |
Consider list of prices named prices. If price is greater than 30, then the 25% discount must be set. If not, then price must be reduced by 3. Check out how can we do it with the for loop.
123456789101112131415161718prices = [20.35, 30.5, 12.65, 8.5, 6.5, 5.8, 40.5] print(prices) prices_upd = [] # Set the for loop for price in prices: # Condition: the element of the list is greater than 30 if price > 30: # Set the 25% discount price *= 0.75 else: # Decrease the price by 3 price -= 3 # Appending values to the upd list prices_upd.append(price) # Print the prices_upd print(prices_upd)
