给大家分享两个PyCharm编辑器的插件，分别是pylint与autopep8，主要用来提高我们在使用python进行自动化测试编写以及性能测试脚本编写过程中的代码质量、可读性与美观性。

pylint：

●	代码检查工具：它可以帮助检查代码中的错误、风格问题等，提高代码质量。●	提供反馈：会指出潜在的问题，并给出相应的建议。

autopep8：

●	代码格式化插件：它可以自动将代码按照一定的规范进行格式化，使代码更加整洁美观。●	遵循风格指南：确保代码符合特定的风格要求。

一、代码规范检查

安装pylint

pip install pylint

pycharm配置

Program(autopep8的安装路径):
C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts\pylint.exeArguments:
--rcfile=.\pylint.conf --output-format=parseable --disable=R -rn --msg-template="{abspath}:{line}: [{msg_id}({symbol}), {obj}] {msg}" $FilePath$Working directory:
$ProjectFileDir$

配置完成后，需要在项目主目录下创建pylint.conf文件，内容如下，直接复制即可（调整文件中的disable的值可以调整代码检查的规则）：

[MASTER]# A comma-separated list of package or module names from where C extensions may
# be loaded. Extensions are loading into the active Python interpreter and may
# run arbitrary code.
extension-pkg-whitelist=# Add files or directories to the blacklist. They should be base names, not
# paths. 选择需要忽略检查的文件夹（在pycharm中使用pylint工具忽略文件夹无效，只能在命令行中生效:pylint --ignore weixin,lib project_name）
ignore=app,venv,install_file,libs# Add files or directories matching the regex patterns to the blacklist. The
# regex matches against base names, not paths.
ignore-patterns=# Python code to execute, usually for sys.path manipulation such as
# pygtk.require().
#init-hook=# Use multiple processes to speed up Pylint. Specifying 0 will auto-detect the
# number of processors available to use.
jobs=1# Control the amount of potential inferred values when inferring a single
# object. This can help the performance when dealing with large functions or
# complex, nested conditions.
limit-inference-results=100# List of plugins (as comma separated values of python modules names) to load,
# usually to register additional checkers.
load-plugins=# Pickle collected data for later comparisons.
persistent=no# Specify a configuration file.
#rcfile=# When enabled, pylint would attempt to guess common misconfiguration and emit
# user-friendly hints instead of false-positive error messages.
suggestion-mode=yes# Allow loading of arbitrary C extensions. Extensions are imported into the
# active Python interpreter and may run arbitrary code.
unsafe-load-any-extension=no[MESSAGES CONTROL]# Only show warnings with the listed confidence levels. Leave empty to show
# all. Valid levels: HIGH, INFERENCE, INFERENCE_FAILURE, UNDEFINED.
confidence=# Disable the message, report, category or checker with the given id(s). You
# can either give multiple identifiers separated by comma (,) or put this
# option multiple times (only on the command line, not in the configuration
# file where it should appear only once). You can also use "--disable=all" to
# disable everything first and then reenable specific checks. For example, if
# you want to run only the similarities checker, you can use "--disable=all
# --enable=similarities". If you want to run only the classes checker, but have
# no Warning level messages displayed, use "--disable=all --enable=classes
# --disable=W". 禁用pylint的某些模块 如 显示： Missing class docstring (missing-docstring) 则 添加 括号中的 missing-docstring 到变量中

运行插件

二、代码格式化

安装autopep8

pip install autopep8

pycharm配置

Program(autopep8的安装路径):
C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts\autopep8.exeArguments:
--in-place --aggressive $FilePath$Working directory:
$ProjectFileDir$

运行插件

点击后，会按照pep8标准执行代码格式化。
