There is more information on the Internet than any human can absorb in a lifetime. What you need is not access to that information, but a scalable way to collect, organize, and analyze it. Web scraping automatically extracts data and presents it in a format you can easily make sense of. We are going to use Python as our scraping language, together with a simple and powerful library, BeautifulSoup.

Next we need to get the BeautifulSoup library using pipa package management tool for Python. Note : If you fail to execute the above command line, try adding sudo in front of each line.

This is the basic syntax of an HTML webpage. Also, HTML tags sometimes come with id or class attributes. The class attribute is used to define equal styles for HTML tags with the same class. We can make use of these ids and classes to help us locate the data we want. Try hovering your cursor on the price and you should be able to see a blue box surrounding it.

If you click it, the related HTML will be selected in the browser console. Now that we know where our data is, we can start coding our web scraper. Open your text editor now!

Now we have a variable, soupcontaining the HTML of the page. Remember the unique layers of our data? BeautifulSoup can help us get into these layers and extract the content with find. Now that we have the data, it is time to save it. The Excel Comma Separated Format is a nice choice. It can be opened in Excel so you can see the data and process it easily.A lot is written about how to tune specific time series forecasting models, but little help is given to how to use a model to make predictions.

Once you can build and tune forecast models for your data, the process of making a prediction involves the following steps:.

So far its been fairly straightforward but tonight I have come across a couple of brick walls and I am wondering if anyone could assist. The below code I am creating is to give me 6 random numbers in a range of 1 to Here are my questions: 1 Why do the numbers print out surrounded in brackets i.

I never know if I am doing it right or wrong. Is it a case of "if it works, then its right?

Here is my code: Code:.With mathematical rigor and narrative flair, Adam Kucharski reveals the tangled history of betting and science. The house can seem unbeatable. In this book, Kucharski shows us just why it isn't. Even better, he shows us how the search for the perfect bet has been crucial for the scientific pursuit of a better world.

This post is based on excerpt from. The house can seem unbeatable, but Kucharski shows us just why it isn't. Whenever a big lottery rollover arrives, interest in math spikes. At first glance, such calculations might seem like a matter of straightforward probability. But as we delve further into lottery strategy, the questions involved become more interesting—and far trickier.

But would you really play such a lottery? Mathematical theory can handle infinite timescales; wallets cannot. To avoid bankruptcy arriving before profits, successful bettors—whether at the blackjack table or the races—often employ bankroll management techniques.

Devised by physicist John Kelly in the s, this aims to maximize the long-term growth of your money, balancing potential profits with risk of loss. For a given bet, the Kelly criterion tells players to wager the following fraction of their total wealth:.

Figure 1: How many tickets should a billionaire buy? This happens when the prize money reaches a certain set limit, and gets re-distributed to the lower prize tiers. How should you pick your tickets to ensure you maximise your chances of picking up a certain prize? In some cases,the best lotto design remains unknown.

Lottery researcher Peter Rosendahl provided an upper bound for the value, when he found numerically a combination of tickets that worked, but the true minimum number of tickets may be lower than this. As well as considering multiple tickets, we also need to account for multiple players.

When roll-downs appear in a lottery, the expect value of a game increases, but so does the chance of splitting the jackpot with others. One option is to turn to psychology, and try to avoid popular numbers—such as birthdays—that would dilute your winnings if you won.

Alternatively, you could try and influence the outcome of the game by brute force. The group were originally from MIT, and their lottery operation had started - naturally - with a college math project. By subscribing you accept KDnuggets Privacy Policy. Subscribe to KDnuggets News.

You have a very consistent coding style which is good. However you seem to use a C naming convention and formating instead of a pythonic. The golden standard for style in python is PEP 8. It explains in excruciating detail how to structure your code.

I whole heartily recommend skimming through it and follow it. This allows you to reuse the functions for later, and is a great thing to always use. The getUserNums is a bit strange. If my input is incorrect, you raise an error. However the second time my input is incorrect it passes just fine.

You could solve this using a while loop instead. The second problem with the snippet above is that you can guess the same number more than once! A third and final problem is that you'r program crashes if the input is not an integer.

There are many solutions for this, a quick and dirty one is shown below. The continue keyword is important as it skips the remainder of the loop. What happens if you remove it? This can be solved as follows. Throughout your code we find what is called Magic numbers.

They are unique values with unexplained meaning or multiple occurrences which could preferably be replaced with named constants. These should optimally be replaced with named constants. In the code below I have changed your variable names, replaced all the magical numbers. I have also made some small changes to your main function.

Lasly I made your Error messages more descriptive: input "Error! Invalid input. Press any key to continue What was wrong with my input? Secondly it is strange to ask the user to press any key to continue.

I've wrote a script to print out lottery combinations. What i'm aiming for is this: There are 6 numbers in the lottery between meaning there are 13, combinations.

I want to start with [1,2,3,4,5,6] and end up at [44,45,46,47,48,49]. So I need to order the results. Also, I've tried converting the list to a string so I can put the results in a big text file, but I'm just printing [] to the text file at the moment.

Wow that's really simple. Thanks Ashwini. Didn't know such a module existed. Wouldn't iterating over the results and writing to a file be better than unpacking the iterator?
