[PYTHON] How to suppress Pycharm's "pep8 indentation is not a multiple of four" and "Variable in function should be lower case" warnings

Introduction

Python development uses Pycharm.

Python Coding style warning

• Variable in function should be lowercase
• pep8 indentation is not a multiple of four (appears when changing the Indent size from 4 half-width spaces to 2)

Is annoying everywhere, so I will put the setting method in Pycharm to suppress this on the back of the leaflet.

Setting method

• ** How to remove Variable in function should be lower case **
• Open ʻInspections with File→Setting and uncheck PEP 8 coding naming convention viloation`
• ** How to erase pep8 indentation is not a multiple of four **
• Open ʻInspections with File→Setting and select PEP 8 coding style viloation` on the search screen in the right pane.
• Add ʻE111 to ʻIgnore errors and execute ʻApply`

Similar warnings in other development environments

• If you use PEP8's Linter in other development environments, you should usually have a setting to Ignore certain errors. For example, in the case of ATOM PEP8 Linter, if you write 'ignoreErrorCodes':'E111, E501' in config.cson Looks good

Supplement about PEP8

About PEP8

• PEP8 is roughly a Python Coding Rule. This article is very helpful
• PEP8 Click here for Japanese translation
• See here for a list of PEP8 Error Codes (http://pep8.readthedocs.org/en/latest/intro.html#error-codes)

Major Coding Rules

• About Indent

• It is recommended to make one indent (Tab) with four Spaces

• If you want to suppress this error, ignore E111 and E114

• About function names and variable names

• Function name, variable name: It is recommended to separate all lowercase letters with _ (set_stream_logger etc.)

• Class name: Upper Camel Case recommended (eg GetImageLocation)

• Other than Pycharm, Flake8 (PEP8 Wrap library) and [pep8-naming (flake8 plugin)](https://github.com/flintwork/ It seems that you should put pep8-naming) and set it to ignore N802 / N806 etc. (I have not tried it)

• 1 line length

• Up to 79 characters per line is recommended

• If you want to suppress this error, ignore E501

• About Import Declaration

• 1 line 1 library Import recommended

• If you want to suppress this error, ignore E401

• Whitespace before and after the operator

• Insert a space before and after operators such as =, ==, <,>, is, in, not in

• If you want to suppress this error, ignore E221 and E222

About PEP8 Check Tool

There are two types of tools, pep8 and ʻautopep8`.

• About pep8
• Tool that tells you where to fix
• Install with pip install pep8 and check pep8 xxx.py --show-source * If you specify .py, the error code and the corresponding part will be spit out as shown below.
• If you want to ignore a particular Error, pep8 xxx.py --ignore = E111, E114, E501 --show-source E111 / 114 is ʻIndent Error, E501 is Line Too Long`

xxx.py:4:1: E302 expected 2 blank lines, found 1
def foo():
^
misc_test.py:5:9: E225 missing whitespace around operator
    msgs=['Hello','World!!']
        ^
misc_test.py:5:18: E231 missing whitespace after ','
    msgs=['Hello','World!!']
                 ^
misc_test.py:9:10: W292 no newline at end of file
    foo()
         ^

• About ʻautopep8`
• It is a tool that even corrects automatically
• Install with pip install autopep8 and want it to be automatically corrected as ʻautopep8 -i xxx.py` * If you specify .py, the contents of File will be corrected without asking questions (so be careful when executing) is)
