It is very important to install Flake8 on the correct version of Python for your needs. If you want Flake8 to properly parse new language features in Python 3.5 (for example), you need it to be installed on 3.5 for Flake8 to understand those features. In many ways, Flake8 is tied to the version of Python on which it runs.

python -m pip install flake8

vim-flake8 is a Vim plugin that runs the currently open file through Flake8, a static syntax and style checker for Python source code. It supersedes both vim-pyflakes and vim-pep8.

Flake8 is a wrapper around PyFlakes (static syntax checker), PEP8 (style checker) and Ned's MacCabe script (complexity checker).

ALE makes use of NeoVim and Vim 8 job control functions and timers to run linters on the contents of text buffers and return errors as text is changed in Vim. This allows for displaying warnings and errors in files being edited in Vim before files have been saved back to a filesystem.

In other words, this plugin allows you to lint while you type.

ALE offers support for fixing code with command line tools in a non-blocking manner with the :ALEFix feature, supporting tools in many languages, like prettier, eslint, autopep8, and more.

ALE acts as a "language client" to support a variety of Language Server Protocol features, including:

• Diagnostics (via Language Server Protocol linters)
• Go To Definition (:ALEGoToDefinition)
• Completion (Built in completion support, or with Deoplete)
• Finding references (:ALEFindReferences)
• Hover information (:ALEHover)
• Symbol search (:ALESymbolSearch)

If you don't care about Language Server Protocol, ALE won't load any of the code for working with it unless needed. One of ALE's general missions is that you won't pay for the features that you don't use.

Pyright is a fast type checker meant for large Python source bases. It can run in a “watch” mode and performs fast incremental updates when files are modified.

This part of the documentation covers all the interfaces of Requests. For parts where Requests depends on external libraries, we document the most important right here and provide links to the canonical documentation.

Requests is an elegant and simple HTTP library for Python, built for human beings.

Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling are 100% automatic, thanks to urllib3.

Beloved Features:

• Requests is ready for today’s web.
• Keep-Alive & Connection Pooling
• International Domains and URLs
• Sessions with Cookie Persistence
• Browser-style SSL Verification
• Automatic Content Decoding
• Basic/Digest Authentication
• Elegant Key/Value Cookies
• Automatic Decompression
• Unicode Response Bodies
• HTTP(S) Proxy Support
• Multipart File Uploads
• Streaming Downloads
• Connection Timeouts
• Chunked Requests
• .netrc Support

Requests officially supports Python 2.7 & 3.6+, and runs great on PyPy.

UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xd1 in position 1: ordinal not in range(128) (Why is this so hard??)
One of the toughest things to get right in a Python program is Unicode handling. If you’re reading this, you’re probably in the middle of discovering this the hard way.

The main reasons Unicode handling is difficult in Python is because the existing terminology is confusing, and because many cases which could be problematic are handled transparently. This prevents many people from ever having to learn what’s really going on, until suddenly they run into a brick wall when they want to handle data that contains characters outside the ASCII character set.

i3ipc-python is a library for controlling i3 window manager and sway. i3 users can use this library to create their own plugin scripts to customize their desktop or integrate i3 into other applications. With this library, you can query the state of the window manager, listen to events, and send commands to i3 to perform window manager actions such as focusing or closing windows.

The main entry point into the features of the library is the Connection class. This class manages a Unix socket connection to the ipc interface exposed by the window manager. By default, the Connection will attempt to connect to the running instance of i3 by using information present in the environment or the running X11 display.

i3's interprocess communication (or ipc) is the interface i3wm uses to receive commands from client applications such as i3-msg. It also features a publish/subscribe mechanism for notifying interested parties of window manager events.

i3ipc-python is a Python library for controlling the window manager. This project is intended to be useful for general scripting, and for applications that interact with the window manager like status line generators, notification daemons, and window pagers.

If you have an idea for a script to extend i3wm, you can add your script to the examples folder.

For details on how to use the library, see the reference documentation.

Network automation to screen-scraping devices is primarily concerned with gathering output from show commands and with making configuration changes.

Netmiko aims to accomplish both of these operations and to do it across a very broad set of platforms. It seeks to do this while abstracting away low-level state control (i.e. eliminate low-level regex pattern matching to the extent practical).

Nornir is an automation framework written in python to be used with python. Most automation frameworks hide the language they are written in by using some cumbersome pseudo-language which usually is almost Turing complete, but lacks tooling to debug and troubleshoot. Integrating with other systems is also usually quite hard as they usually have complex APIs if any at all. Some of the other common problems of those pseudo-languages is that are usually quite bad at dealing with data and re-usability is limited.

Nornir aims to solve those problems by providing a pure python framework. Just imagine Nornir as the Flask of automation. Nornir will take care of dealing with the inventory where you have your host information, it will take care of dispatching the tasks to your devices and will provide a common framework to write “plugins”.

PyOTP is a Python library for generating and verifying one-time passwords. It can be used to implement two-factor (2FA) or multi-factor (MFA) authentication methods in web applications and in other systems that require users to log in.

Open MFA standards are defined in RFC 4226 (HOTP: An HMAC-Based One-Time Password Algorithm) and in RFC 6238 (TOTP: Time-Based One-Time Password Algorithm). PyOTP implements server-side support for both of these standards. Client-side support can be enabled by sending authentication codes to users over SMS or email (HOTP) or, for TOTP, by instructing users to use Google Authenticator, Authy, or another compatible app. Users can set up auth tokens in their apps easily by using their phone camera to scan otpauth:// QR codes provided by PyOTP.

There’s an amazing amount of data available on the Web. Many web services, like YouTube and GitHub, make their data accessible to third-party applications through an application programming interface (API). One of the most popular ways to build APIs is the REST architecture style. Python provides some great tools not only to get data from REST APIs but also to build your own Python REST APIs.

In this tutorial, you’ll learn:

• What REST architecture is
• How REST APIs provide access to web data
• How to consume data from REST APIs using the requests library
• What steps to take to build a REST API
• What some popular Python tools are for building REST APIs

By using Python and REST APIs, you can retrieve, parse, update, and manipulate the data provided by any web service you’re interested in.

Click is a Python package for creating beautiful command line interfaces in a composable way with as little code as necessary. It’s the “Command Line Interface Creation Kit”. It’s highly configurable but comes with sensible defaults out of the box.

It aims to make the process of writing command line tools quick and fun while also preventing any frustration caused by the inability to implement an intended CLI API.

Click in three points:

• arbitrary nesting of commands

• automatic help page generation

• supports lazy loading of subcommands at runtime

Mitogen is a Python library for writing distributed self-replicating programs.

There is no requirement for installing packages, copying files around, writing shell snippets, upfront configuration, or providing any secondary link to a remote machine aside from an SSH connection. Due to its origins for use in managing potentially damaged infrastructure, the remote machine need not even have free disk space or a writeable filesystem.

It is not intended as a generic RPC framework; the goal is to provide a robust and efficient low-level API on which tools like Salt, Ansible, or Fabric can be built, and while the API is quite friendly and comparable to Fabric, ultimately it is not intended for direct use by consumer software.

The focus is to centralize and perfect the intricate dance required to run Python code safely and efficiently on a remote machine, while avoiding temporary files or large chunks of error-prone shell scripts, and supporting common privilege escalation techniques like sudo, potentially in combination with exotic connection methods such as WMI, telnet, or console-over-IPMI.
