Dask is a powerful open-source Python parallel computing framework. Dask scales Python programs from single-core local workstations to huge distributed cloud clusters. Dask provides a familiar user experience by replicating the APIs of other PyData ecosystem programs like Pandas, Scikit-learn, and NumPy. It also offers low-level APIs that allow programmers to execute bespoke algorithms concurrently.

Scraping Google SERPs (search engine result pages) is as straightforward or as complicated as the tools we use. For this tutorial, we'll be using Scrapy, a web scraping framework designed for Python. Python and Scrapy combine to create a powerful duo that we can use to scrape almost any website. Scrapy has many useful built-in features that will make scraping Google a walk in the park without compromising any data we would like to scrape. For example, with Scrapy all it takes is a single command to format our data as CSV or JSON files – a process we would have to code ourselves otherwise.

We live in a time where data is supreme. Our private details, financial arrangements, careers, and amusement have been digitized and stored as data. Due to the greater volume of data generated, there is a more significant need to research and retain it. If you're conscious of the current market environment, you've probably noticed that the data science field is flourishing. Data Science signifies generated value from data, and it all comes down to comprehending the data and processing it to obtain actionable & insightful value from it.

Python provides a lot of libraries to help developers with their work. Which of them will be the most popular in 2020? And which are worth your time? Here are our picks for the 13 top Python libraries. Python is one of the most popular programming languages.

As a junior data scientist, most of the times training data are ready for me to train the model (either by accessing database/external csv file provided). However, dataset is not always available for us, we need scraping skill to make our life easier. My friend and I decided to start this mini-project which contains the whole process from scraping, to exploratory and finally perform some simple prediction using various machine learning models within 1 day as a small challenge for our own. We can't wait to share our findings and hopefully you could enjoy reading it. Besides, feel free to reach us by commenting below if you find anything unclear/spot some points we have miss out!:) We will be scrapping TOP 100 COOLEST TECH GADGETS OF 2018 from bestproducts.com

On this new post series, we will analyze hundreds of thousands of articles from TechCrunch, VentureBeat and Recode to discover cool trends and insights about startups. These are the types of questions we aim to answer with this analysis. On this first post, we will cover how Scrapy can be used to get all the articles ever published on these tech news sites and how MonkeyLearn can be used for filtering these crawled articles by whether they are about startups or not. We want to create a dataset of startup news articles that can be used for studying trends later on. On the second post, we will create text classifiers that do analysis on the actual content of the startup articles. Is it a news about acquisition? Finally, on the third post we will use the data we got here, and the classifiers from the second post, to answer our questions.

We are currently in an era of data explosion, where millions of tweets, articles, comments, reviews and the like are being published everyday. Developers are taking advantage of the abundance of data and using things like web scraping to do all kinds of cool things. Sometimes web scraping is not enough; digging deeper and analyzing the data is often needed to unlock the true meaning behind the data and discover valuable insights. On this tutorial we will cover how you can use MonkeyLearn and Scrapy to build a machine learning model that will help you analyze vast amounts of web scraped data in a cost-effective way. We will use Scrapy to extract hotel reviews from TripAdvisor and use those reviews as training samples to create a machine learning model with MonkeyLearn.
