Adding commas in inputs in Python?

Question

I want to make this program in Python 3.3.2 which asks you for the radius and height of a cylinder which you have to type in as radius, height Here is the current code:

if response=="vol":
    radius = float(input("What is the radius and height of the cylinder? (e.g. 32, 15): "))

How should I change it? After that I will calculate its volume: V = hπr² How will I do this with your method?

radius, height = [float(part) for part in input("What is the radius and height of the cylinder? (e.g. 32, 15): ").split(',')]

The split splits the input at the comma into two parts; the for is part of a list comprehension, which creates a list by applying the same action to each result.

@JasonSperske, yes it would, but Guido prefers list comprehensions and I'm not going to argue with him.

Is the con readability or some shortsightedness in the map() function?

Hi I don't get this part of the code: [float(part) for part in input

@TimTimmy, look at docs.python.org/2/tutorial/…. Instead of using a range as in the example, I'm using the results of split which returns strings in a list.

I've been working my way through The Little Schemer so this in really fascinating to me. Thanks for the link :)
