Set Up for Mac (Python)

What is this

Here is a memo for building a development environment in Python in case you buy a new macPC.

System Preferences

Confirm conversion in Japanese input once instead of twice

It has nothing to do with development, but it feels awkward, so I'll change it.

--Select "System Preferences"-> "Keyboard"-> "Input Source" from Launchpad etc. --With Japanese selected from the left side of the screen, scroll the right screen and check "Windows-like key operation". ――You may like it, but if you uncheck "Live conversion", it will not be converted without permission.

Change the background color of the terminal

The default setting is black on a white background, which makes my eyes tired and uncomfortable, so I change it (generally, this is an image with many black backgrounds).

--Open a terminal from Launchpad etc. --Select "Terminal"-> "Preferences"-> "Profile" from the menu at the top left of the screen. --You can change it freely on the "Text" tab. There is also a template on the left side of the screen, so you can set it from there (if you select a template, select "Default" at the bottom of the screen).

Homebrew Package management system for mac.

-Copy the command to install from the here site and execute it in the terminal (installation takes a little time). Example.

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

--Execute the following command and check if the installation is completed normally.

$ brew --version
Homebrew 2.5.

Git Version control system.

--Execute the following command to install git.

$ brew install git

--Execute the following command and check if the installation is completed normally.

$ git —-version
git version 2.28.0

• If you have a Git account, you may want to set it in config with the following command.

$ git config --global user.name "John Doe"
$ git config --global user.email [email protected]

Python Interpretered programming language. It is often used in machine learning.

--Execute the following command.

$ brew install python3

--Confirm execution in interactive mode. You can exit interactive mode by typing ʻexit () `.

$ python3
>>> print("Hello world!")
Hello world!

ANACONDA Distribution for Python and R language for Data Scientist.

-Open the here page. ――If you scroll down the screen, you will reach the screenshot below. --Click the 64-Bit Graphical Installer (462 MB) boxed in red to download. --Click on the installed .pkg file and follow the instructions to install.

pip A package management system for installing and managing packaged software written in Python.

-Check if you have / usr / bin / easy_install (usually it should be pre-installed). --Command example: ls / usr / bin / easy_install --Execute the following command.

sudo easy_install pip

--Check the execution.

$ pip --version
pip 20.2.3

Visual Studio Code (hereinafter VS Code)

An editor developed by Microsoft.

-Open here. --Click Download for Mac to download. --Extract the downloaded zip file. --Drag and drop the application written as Visual Studio Code to the application folder.

About VS Code settings

Describe what you usually set when developing. --Packages to be installed in advance.

$ pip install flake8
$ pip install autopep8

--Extensions in VS Code - Python - Python for VSCode - Python Docstring Generator

• setting.json

{
    "python.linting.pylintEnabled": false,
    "python.linting.flake8Enabled": true,
    "files.autoSave": "afterDelay",
    "files.autoSaveDelay": 1000,
    "python.linting.lintOnSave": true,
    "python.formatting.provider": "autopep8",
    "python.linting.flake8Args": [
        "--ignore=E501",
    ],
    "python.formatting.autopep8Args": [
        "--aggressive", "--aggressive",
    ],
    "autoDocstring.docstringFormat": "numpy",
}

At the end

I wrote it as a memorandum that I will never forget what I put in. If there are any omissions, I will add them as needed.
