Brandon Rhodes published a post today about the Decorator Pattern and how that translates into Python. He explains the manual way that the pattern can be implemented in Python as a wrapper, as well as how you can try to minimise the amount of work you need to do by overriding special methods of a Python object. The wrapt package I authored was purpose built for this task of creating wrappers which Brandon describes, and much more. To avoid some of the name confusion around Decorator Pattern versus Python decorators, which Brandon highlights as an issue, I tend to refer to the wrappers as transparent object proxies. wrapt
Today’s post focuses on applying linear regression techniques to a less-than-ideal dataset. In order to do so, I need a scenario from which to work. As of this writing, the MLB free agent signing period (or ‘Hot Stove’ as it is affectionately named) is in full effect. Therefore, I chose the following problem statement as my challenge: my client, a professional baseball team, is interested in offering a contract to a free agent starting pitcher and wants a recommendation for the annual salary it should propose. Now that I have my problem, I can begin working on the answer! data science,
jupyter Or how to run Headless Chrome on AWS Lambda together with Python, Selenium and Chromedriver Selenium, lamda, chromedriver MoviePy (full documentation) is a Python library for video editing: cutting, concatenations, title insertions, video compositing (a.k.a. non-linear editing), video processing, and creation of custom effects. See the gallery for some examples of use. video You already know the longer it takes to detect a problem, the more expensive it is to resolve. Your testing needs to happen earlier in the development pipeline while taking into account all aspects of privacy, security and monitoring. Read the 4-part eBook to learn how to detect problems earlier in your DevOps testing processes by. advert, devops The problem was, once we change something in the CSS/JS, that change was not getting reflected on the client side and browser was taking the old files from the cache. To avoid this, we needed a mechanism to refresh the cache once anything has changed in the CSS/JS. The obvious approach was to change the name or attach a version number to a CSS file each time we make a change. But we wanted this process to be automated so we came across Django-compressor. django Python 3.4 introduced a new standard library for dealing with files and paths called pathlib?—?and it’s great! core-python jupyter In my previous post on the new open source Python Bounter library we discussed how we can use its HashTable to quickly count approximate item frequencies in very large item sequences. Now we turn our attention to the second algorithm in Bounter, CountMinSketch (CMS), which is also optimized in C for top performance. counter Learn how to create PDFs using the popular Python programming language and the ReportLab toolkit. Kickstarter campaign. kickstarter A Python application that sync Github Gists and save them to Evernote notebook as screenshots. project, gist, evernote The main goal of this reading is to understand enough statistical methodology to be able to leverage the machine learning algorithms in Python’s scikit-learn library and then apply this knowledge to solve a classic machine learning problem. The first stop of our journey will take us through a brief history of machine learning. Then we will dive into different algorithms. On our final stop, we will use what we learned to solve the Titanic Survival Rate Prediction Problem. machine learning So the context is this; a zip file is uploaded into a web service and Python then needs extract that and analyze and deal with each file within. In this particular application what it does is that it looks at the file's individual name and size, compares that to what has already been uploaded in AWS S3 and if the file is believed to be different or new, it gets uploaded to AWS S3. code snippet, zip Projects minigo - 1201 Stars, 83 Fork An open-source implementation of the AlphaGoZero algorithm. captivox - 47 Stars, 3 Fork cool animations with pyqt5 and parametrics cryptoCMD - 37 Stars, 3 Fork Cryptocurrency historical market price data scraper in Python tinfoleak - 28 Stars, 2 Fork The most complete open-source tool for Twitter intelligence analysis. a toolset for autogenerating rust APIs and translating structs.
