Python Weekly

Welcome to issue 344 of Python Weekly. Let's get straight to the links this week.
Complete Python Bootcamp: Go from zero to hero in Python
Learn Python like a Professional! Start from the basics and go all the way to creating your own applications and games!


PyGotham 2018 Call for Proposals
Anyone interested in speaking is encouraged to submit a proposal. There are no restrictions on topics, but we recommend they be of interest to Pythonistas. Talks will fill slots of 25 minutes and 40 minutes, including time for questions and answers.

Articles, Tutorials and Talks

Accelerating Deep Neuroevolution: Train Atari in Hours on a Single Personal Computer
Applying hardware acceleration to deep neuroevolution in what is now an open source project, Uber AI Labs was able to train a neural network to play Atari in just a few hours on a single personal computer, making this type of research accessible to a far greater number of people.

Testing Django with pytest: debugging a teardown failure
This is the story of a debugging odyssey that could have been avoided by a more careful reading of documentation. I’m telling it not only to draw attention to the documentation, but also because it’s the story of a fun hunt. And there are good lessons to be learned for any of us.

Pipenv: A Guide to the New Python Packaging Tool
Pipenv is a packaging tool for Python that solves some common problems associated with the typical workflow using pip, virtualenv, and the good old requirements.txt. This guide goes over what problems Pipenv solves and how to manage your Python dependencies with it.

Running Keras models on iOS with CoreML
In last week’s post, you learned how to train a Convolutional Neural Network (CNN) with Keras. In this post, we’re going to take this trained Keras model and deploy it to an iPhone and iOS app using what Apple has dubbed “CoreML”, an easy-to-use machine learning framework for Apple applications.

Bayesian Linear Regression in Python: Using Machine Learning to Predict Student Grades Part 1
In part 1 of the Bayesian Machine Learning project, we outline our problem, performe a full exploratory data analysis, select our features, and establish benchmarks.
  • Part 2 - In this part, we will implement Bayesian Linear Regression in Python to build a model. After we have trained our model, we will interpret the model parameters and use the model to make predictions. 

ESP8266 Garage Door Monitor/Controller [part 1]
Prototype for a garage door monitor/controller using MicroPython and an ESP8266.

How to create a 2D game with Python and the Arcade library
Learn how to get started with Arcade, an easy-to-use Python library for creating 2D video games.

Flask Webcast #2: Request and Application Contexts
This session discusses the Flask contexts and the very confusing errors that these can cause when used incorrectly. It includes the Q&A portion as well.

Build an Instagram “Pin” Effect in Python with Dlib
In this post, we’ll build an Instagram “Pin” effect in Python, where an image is made to stay in specific position while the camera moves around it. This pin effect is now much less impressive now that Apple’s ARKit has become commonplace, but working with a simple interface like Dlib’s correlation tracker gives us a great starting point without needing sensor data like in the iPhone. So we’ll build a tool for creating videos with pinned images in them in Python. Along the way, we’ll build an interactive environment to test candidate positions for our correlation trackers, allowing us to preview just how well our places will be tracked.

Python 3's pathlib Module: Taming the File System
How to effectively work with file system paths in Python 3 using the new "pathlib" module in the standard library.

Untangling our Python Code
The previous posts about The Great Khan Academy Python Refactor of 2017 and Also 2018 answered two questions: why and how did we refactor all of our Python code? In this post, I want to look closer at a major goal of this project: cleaning up dependencies between parts of our Python codebase.

Writing a simple SOCKS server in Python
This article explains how to write a tiny and basic SOCKS 5 server in Python 3.6. I am assuming that you already have a basic understanding of proxy servers.

Create TUI on Python
In this article I will talk about the npyscreen — library for creating console applications.

Transforming Python ASTs to Optimize Comprehensions
Python comprehensions can have duplicate function calls (e.g. [foo(x) for x in ... if foo(x)]). If these function calls are expensive, we need to rewrite our comprehensions to avoid the cost of calling them multiple times. In this post, we solve this by writing a decorator that converts a function in to AST, optimizes away duplicate function calls and compiles it at runtime in ~200 lines of code.

Deep Learning with TensorFlow - Second Edition: Explore neural networks with Python
Delve into neural networks, implement deep learning algorithms, and explore layers of data abstraction with the help of this comprehensive TensorFlow guide. Throughout the book, you'll learn how to implement deep learning algorithms for machine learning systems and integrate them into your product offerings, including search, image recognition, and language processing. Additionally, you'll learn how to analyze and improve the performance of deep learning models. This can be done by comparing algorithms against benchmarks, along with machine intelligence, to learn from the information and determine ideal behaviors within a specific context.
