I can't get a floating point number to calculate in a simple progr
Posted 22 March 2013 - 01:25 PM
I'm trying to learn Python on my own and I'm doing little projects to learn the nuances of the language. In the simple script below I'm trying to take a radius of a circle as input from a user and print out the circumference of the circle. It always rounds to a whole number though and I can't figure out why. Can someone give me some hints or point me in the right direction as to why? I'm not looking for full solutions here just a little direction.

%f (for floating point) works too. The format specifier %d is used to print integers and, as you noticed, it will convert anything that isn't an integer to an integer before printing it.
