Python for Data Analysis By Wes McKinney

This book cares with the nuts and bolts of manipulating, processing, cleaning, and crunching data in Python. This Book is to supply a guide to the parts of the Python programming language and its data-oriented library ecosystem and tools which will equip you to become an efficient data analyst. While “data analysis” is within the title of the book, the main target is specifically on Python programming, libraries, and tools as against data analysis methodology. this is often the Python programming you would like for data analysis.0

Why Python for Data Analysis?

For many people, the Python programming language has strong appeal. Since its introduction in 1991, Python has become one among the foremost popular interpreted programming languages, along side Perl, Ruby, etc. . Python and Ruby became especially popular since 2005 approximately for building websites using their numerous web frameworks, like Rails (Ruby) and Django (Python). Such languages are often called scripting languages, as they will be wont to quickly write small programs, or scripts to automate other tasks. I don’t just like the term “scripting language,” because it carries a connotation that they can't be used for building serious software. Among interpreted languages, for various historical and cultural reasons, Python has developed an outsizes and active scientific computing and data analysis community. within the last 10 years, Python has gone from a bleeding-edge or “at your own risk” scientific computing language to at least one of the foremost important languages for data science, machine learning, and general software development in academia and industry. For data analysis and interactive computing and data visualization, Python will inevitably draw comparisons with other open source and commercial programming languages and tools in wide use, such as R, MATLAB, SAS, Stata, et al. . In recent years, Python’s improved support for libraries (such as pandas and scikit-learn) has made it a well-liked choice for data analysis tasks. Combined with Python’s overall strength for general-purpose software engineering, it's a superb option as a primary language for building data applications.

BUILDING A TINDER BOT WITH PYTHON

I have included a function for automating  the method  of getting an auth token for the Tinder bot  to figure  (Tinder Token Retriever). Shout  bent  the developer!   to ascertain  a post of the code, view this post: Automatic Tinder Authentication Token Retriever in Python. The update has been included  within the  code file  that's  linked below.   thanks to  this update, the manual process  that's  described below for obtaining an auth token  is no  longer needed. I keep it included  within the  blog post, however, for reference  just in case  the automated code ever stops working.

Computer Vision: Algorithms and Applications

As humans,we perceive the three-dimensional structure of the planet around us with apparent ease. Think of how vivid the three-dimensional percept is once you check out a vase of flowers sitting on the table next to you. You can tell the form and translucency of every petal through the subtle patterns of sunshine and shading that play across its surface and effortlessly segment each flower from the background of the scene The forward models that we use in computer vision are usually developed in physics (radiometry, optics, and sensor design) and in computer graphics . Both of these fields model how objects move and animate, how light reflects off their surfaces, is scattered by the atmosphere, refracted through camera lenses (or human eyes), and finally projected onto a flat (or curved) image plane. While computer graphics aren't yet perfect (no fully computer animated movie with human characters has yet succeeded at crossing the uncanny valley2 that separates real humans from...
