Setting up Your Environment
APPENDIX A Setting Up Your Environment Choosing the correct tools to work with asyncio is a non-trivial choice, since it can significantly impact the availability and performance of asyncio. In this appendix, we discuss the interpreter and the packaging options that influence your asyncio experience. The Interpreter Depending on the API version of the interpreter, the syntax of declaring coroutines change and the suggestions considering API usage change. (Passing the loop parameter is considered deprecated for APIs newer than 3.6, instantiating your own loop should happen only in rare circumstances in Python 3.7, etc.) Availability Python interpreters adhere to the standard in varying degrees. This is because they are implementations/manifestations of the Python language specification, which is managed by the PSF. At the time of this writing, three relevant interpreters support at least parts of asyncio out of the box: CPython, MicroPython, and PyPy. © Mohamed Mustapha Tahrioui 2019 293 M. M. Tahrioui, asyncio Recipes, https://doi.org/10.1007/978-1-4842-4401-2 APPENDIX A SeTTinG Up YouR EnViROnMenT Since we are ideally interested in a complete or semi-complete implementation of asyncio, our choice is limited to CPython and PyPy. Both of these products have a great community. Since we are ideally using a lot powerful stdlib features, it is inevitable to pose the question of implementation completeness of a given interpreter with respect to the Python specification. The CPython interpreter is the reference implementation of the language specification and hence it adheres to the largest set of features in the language specification. At the point of this writing, CPython was targeting API version 3.7. -
Python Crypto Misuses in the Wild
Python Crypto Misuses in the Wild Anna-Katharina Wickert Lars Baumgärtner [email protected] [email protected] Technische Universität Darmstadt Technische Universität Darmstadt Darmstadt, Germany Darmstadt, Germany Florian Breitfelder Mira Mezini [email protected] [email protected] Technische Universität Darmstadt Technische Universität Darmstadt Darmstadt, Germany Darmstadt, Germany ABSTRACT 1 INTRODUCTION Background: Previous studies have shown that up to 99.59 % of the Cryptography, hereafter crypto, is widely used nowadays to protect Java apps using crypto APIs misuse the API at least once. However, our data and ensure confidentiality. For example, without crypto, these studies have been conducted on Java and C, while empirical we would not be able to securely use online banking or do online studies for other languages are missing. For example, a controlled shopping. Unfortunately, previous research results show that crypto user study with crypto tasks in Python has shown that 68.5 % of the is often used in an insecure way [3, 4, 7, 9, 11]. One such problem is professional developers write a secure solution for a crypto task. the choice of an insecure parameter, like an insecure block mode, for Aims: To understand if this observation holds for real-world code, crypto primitives like encryption. Many static analysis tools exist we conducted a study of crypto misuses in Python. Method: We to identify these misuses such as CryptoREX [13], CryptoLint [4], developed a static analysis tool that covers common misuses of5 CogniCryptSAST [8], and Cryptoguard [12]. different Python crypto APIs. With this analysis, we analyzed 895 While these tools and the respective in-the-wild studies concen- popular Python projects from GitHub and 51 MicroPython projects trate on Java and C, user studies suggest that the existing Python for embedded devices. -
Pyglet Documentation Release 1.2Alpha1

It supports windowing, user interface event handling, OpenGL graphics, loading images and videos and playing sounds and music. It works on Windows, OS X and Linux. CONTENTS 1 pyglet Documentation, Release 1.2alpha1 2 CONTENTS CHAPTER ONE PROGRAMMING GUIDE: 1.1 pyglet Programming Guide breadcrumb Programming Guide The pyglet Programming Guide provides in-depth documentation for writing applications that use pyglet. Many topics described here reference the pyglet API reference, provided separately. If this is your first time reading about pyglet, we suggest you start at Writing a pyglet application. 1.1.1 Installation pyglet does not need to be installed. Because it uses no external libraries or compiled binaries, you can run it in-place. You can distribute the pyglet source code or runtime eggs alongside your application code (see Distribution). You might want to experiment with pyglet and run the example programs before you install it on your development machine. To do this, add either the extracted pyglet source archive directory or the compressed runtime egg to your PYTHONPATH. On Windows you can specify this from a command line: set PYTHONPATH c:\path\to\pyglet-1.1\;%PYTHONPATH% On Mac OS X, Linux or on Windows under cygwin using bash: set PYTHONPATH /path/to/pyglet-1.1/:$PYTHONPATH export PYTHONPATH or, using tcsh or a variant: setenv PYTHONPATH /path/to/pyglet-1.1/:$PYTHONPATH If you have downloaded a runtime egg instead of the source archive, you would specify the filename of the egg in place of pyglet-1.1/. -

Pdf for a Detailed Explanation, Along with Various Techniques for Debouncing
MicroPython Documentation Release 1.11 Damien P. George, Paul Sokolovsky, and contributors May 29, 2019 CONTENTS i ii CHAPTER ONE MICROPYTHON LIBRARIES Warning: Important summary of this section • MicroPython implements a subset of Python functionality for each module. • To ease extensibility, MicroPython versions of standard Python modules usually have u (“micro”) prefix. • Any particular MicroPython variant or port may miss any feature/function described in this general docu- mentation (due to resource constraints or other limitations). This chapter describes modules (function and class libraries) which are built into MicroPython. There are a few categories of such modules: • Modules which implement a subset of standard Python functionality and are not intended to be extended by the user. • Modules which implement a subset of Python functionality, with a provision for extension by the user (via Python code). • Modules which implement MicroPython extensions to the Python standard libraries. • Modules specific to a particular MicroPython port and thus not portable. Note about the availability of the modules and their contents: This documentation in general aspires to describe all modules and functions/classes which are implemented in MicroPython project. However, MicroPython is highly configurable, and each port to a particular board/embedded system makes available only a subset of MicroPython libraries. For officially supported ports, there is an effort to either filter out non-applicable items, or mark individual descriptions with “Availability:” clauses describing which ports provide a given feature. With that in mind, please still be warned that some functions/classes in a module (or even the entire module) described in this documentation may be unavailable in a particular build of MicroPython on a particular system. -
