This simple isprime(number) function checks if the given integer number is a prime number and returns True or False. The function makes sure that the number is a positive integer, and that 1 is not considered a prime number. To find out if an integer n is odd one can use `n & 1`, to check for even one can then use `not n & 1` or the more traditional `n % 2 == 0` which is about 30% slower.

# Introduction # This tutorial provides guidance on gathering data through web-scraping. However, to demonstrate the real-life issues with acquiring data, a deep-dive into a specific, complicated example is needed. The problem chosen, acquiring the geographic coordinates of gas stations in a region, turns into an interesting math problem that, eventually, involves "sacred geometry". ## Application Programming Interfaces (API's) ## No matter which Data Science Process [model](https://www.kdnuggets.com/2016/03/data-science-process-rediscovered.html) you subscribe to, actually acquiring data to work with is necessary. By far the most straightforward data source is a simple click-to-download in a standardized file format so you can utilize a parsing …

I like Agile, I really do but a few times it has me walk out on the process as a few think that everyone must "buy in." That's just part of the problems I've run into and kind of glad I'm no longer on such teams. In fact if a company does go "all in" on Agile I may want to short their stock. I think it works until they try to forget what the real goals are. The real goal is to get the product out the door. Some folk love to get wrapped up in the process. The …

As I continue my conversion from vbScript to Python I am finding the gotchas. For example... A lot of my utility scripts take a file name or a file pattern as a parameter. My script, bitrate.vbs, for example allows me to invoke it as bitrate file bitrate pattern Technically file and pattern are identical since specifying a file is really just specifying a pattern that matches up to one file. To get file listings in vbScript I would just spawn a dos `dir` command and grab the output from stdout. In Python, however, they provide what I thought was a …

I'm having a problem with my python installation. The packages that came with the installation work just fine but when I try to use other installed packages I run into problems. For example, I installed a package `pymsgbox` using pip from an admin shell. When I run a sample script from the command line as in `sample`, I get ModuleNotFoundError: No module named 'pymsgbox' but when I run it by `python sample.py` it works fine. Likewise if I load it into IDLE and run it from there. Suggestions?

When working with TCP client sockets I often find myself frustrated with the lack of event-driven support. I usually end up writing a whole bunch of code to determine disconnects, reconnecting, etc and I figuired it's time to just write my own class for this stuff. I figuired I'd share it with all of you. The implementation is quite simple, I'll provide an example below. I have XML commented all the public properties and methods, the rest is up to you to figuire out if you want to make any changes! public partial class Form1 : Form { EventDrivenTCPClient client; …
