Hi. I added self to parts of the code. But after making an instance and using the setData method it gave out an AttributeError. >>> from parallel import Parallel >>> class LightsHandle(Parallel): ... def __init__(self): ... pass ... def setData(self, data): ... Para

[Tutor] Need help with using methods in a base class

Hi. I am having some difficulty using methods from a base class. I have 2 classes. The first one is Parallel which is inside the module parallel. The methods useful to me from this class are setDataStrobe(), setAutoFeed(), setInitOut(), setSelect(), and setData(). The second one is derived from t

Re: [Tutor] Need help with Factorial algorithm using Python

Wow. What a group. Terry, don't feel bad about the answer. I already derived it using all the information I got yesterday. Your solution is a very nice addition to what I learned, and I appreciate that very much. Again, thanks to everyone who provided hints, equations, proofs, and logic paths

Chris, Thank you very much for this. It is very helpful. I will check my answer against yours in the morning. Robert Chris Fuller wrote: I spent the day mulling over this problem, and then implemented my solution when I got home. This is for the easier problem of 7**8 zeros: On my linux

Re: [Tutor] Need help with Factorial algorithm using Python

I spent the day mulling over this problem, and then implemented my solution when I got home. This is for the easier problem of 7**8 zeros: On my linux box, running something around 2 GHz, my script runs for about two minutes and the answer is 23059225. You can verify your code to that. I ch

Re: [Tutor] Need help with Factorial algorithm using Python

Thank you  very much for the help and the math explanation from Omer.  Much of my math background is based on  brute force methodology. Obviously, things have changed. Really changed. Time to do some reading about regex. And here I thought I was slick working with lists and strings. Robert

[Tutor] Need help with Factorial algorithm using Python

I am using both the THINK PYTHON text and the Challenge-You website to learn Python. I am doing reasonably well and certainly enjoy the available challenges. I am currently attempting to work a challenge known as the 'Zeros of a Factorial' challenge located at http://www.challenge-you.com/ch
