STEP 1

Part of the whole

For a point number, use float. In Python, the decimal part is separated by a point, not a comma.

weight = float(input("Вес? "))

✦ The answer 2.5 will be 2.5.

STEP 2

With fractional numbers can be considered the same as with wholes.

weight = float(input("Вес? "))
print(weight + 0.5)

✦ Type 2.5 and 3.0 will appear.

IN-CLASS PRACTICE

Reprint the example. The fractional number is entered through float.

length = float(input("Длина? "))
print(length + 1.5)

HOMEWORK

Ask the fractional price, save it in price and output the price plus 0.5. Think of the text yourself.
