Python code specification tool Flake8

The Python code specification tool Flake8 requires code writing, especially in the team; otherwise, Google will not release various coding specifications, which are familiar with Google C ++ style guidelines, google Python style guide.

Are these specifications useful? It is useful and useless. unless you have a good mind, you need to coding and use the specifications. Otherwise, we still need a tool to do this. Fortunately, there are more than one python tool to help us do this. Let's get off your feet and get started.

Pylint

I have used it, and it turns purple. I don't know who is so boring. can we make pythoner so happy when the rules are set so dead? We don't see rubyer. what does Matz advocate? Happy Coding? So I still use it, because I don't need to be so crazy ~ If you want to install it, it is also simple:

Easy_install pylint // maybe nedd root

Pep8

As the name suggests, it comes from the famous PEP 8 in the Python community. Basically, this is the right way to write code, but this is not perfect. the installation is as follows:

Easy_install pep8 // maybe nedd root

Pyflakes

The Python program passive detection tool is really passive enough. according to the author, it is fast and not powerful enough, but it can still ~

Easy_install pyflakes // maybe nedd root

Flake8

This is my recommendation, but it does not affect other people's liking for pylint. In fact, this buddy is a mass integrator and is packaged with the following three tools:

PyFlakes

Pep8

Ned Batchelder's McCabe script

The advantage is not mentioned. The key is to be scalable. here we are very clear: https://pypi.python.org/pypi/flake8/2.0. The installation is as follows:

Easy_install flake8 // maybe nedd root

If you like Git like me, you are also pyhoner, and there are benefits to write the following code into. git/hooks/pre-commit:

#! /Usr/bin/env python

Import sys

From flake8.hooks import git_hook

COMPLEXITY = 12

STRICT = True

The code will not be explained. the official document is clearly written: http://flake8.readthedocs.org/en/latest/vcs.html?git-hook. If your pre-commit script already has rules, it's okay. Call python in shell.

If you like vim

Vim, one of the two major artifacts, naturally requires plug-ins to enjoy the above tools:

Nvie/vim-flake8

Vim-scripts/pylint. vim

If you see the list above, you should know what I'm talking about. that's right. use vundle to install it:

"Flake8 plugin for Vim.

Bundle 'example E/vim-flake8'

"Compiler plugin for python style checking tool.

Bundle 'vim-scripts/pylint. vim'

Autocmd FileType python compiler pylint

If you really don't know vundle, it's time to use her: https://github.com/gmarik/vundle. If you think this is troublesome, use my vimrc directly. here:

Git clone https://github.com/icocoa/icocoa-vimrc.git -- recursive vimrc // icocoa is my another account in GitHub
