Brief Intro to Python for Statistics By Ryan Cole

What is Python? Python is a popular object-oriented programming language Scripting language, so is compiled in real time Major features: Ease of access elegant syntax large standard library, including interfacing with multiple software layers Disadvantages: Code base is fractured somewhat (two major versions are currently 3.6 and 2.7) Not intended for high performance

How popular is ‘popular’?

Compare to 2014

Where do I get it? Recommended: Install Python 3 using Anaconda https://www.anaconda.com/download/ Platform for data science Includes virtual environments Includes Spyder IDE

Great, how do I learn? Lots of resources online General Python: www.codeacademy.com Free interactive python tutorial (also basic SQL) Geared towards web development but great for basic structure Data Science with Python: Python Data Science Handbook, by Jake VanderPlas

Notable Packages for Python SciPy open-source software for mathematics, science, and engineering that includes: Pandas uses data frames similar to R, particularly tidyverse package in R NumPy array package useful for computation Matplotlib for visualization – include Seaborn for quick boost to quality StatsModels Classes and functions to estimate statistical models and conduct tests Tested for correctness Graphics output is less than optimal Scikit learn Popular machine learning suite with a number of procedures implemented
