Python language is cross-platform, the latest version is 3.8.1, download see here .
The main purpose of this chapter is installed Python programming environment, and run a Hello World program.
Host I chose Oracle Linux 7, the use of vagrant installation, see here . So part of Windows and MacOS will skipped.
Editor authors recommend that Sublime Text , which implies the need for a graphical interface.
vi enhanced version of vim syntax highlighting:
If vim is not installed, you can:
$ sudo yum -y install vim-enhanced
$ alias vi='vim' # 无需设置，在/etc/profile.d/vim.sh中会设置
So my advice is to use the Linux vim, Windows, then on Sublime Text and Visual Studio Code a second election.
But I still installed under Windows Sublime Text, after all, it also supports markdown, you can write documentation available.
sublime text installation on Linux see here :
sudo rpm -v --import https://download.sublimetext.com/sublimehq-rpm-pub.gpg
sudo yum-config-manager --add-repo https://download.sublimetext.com/rpm/stable/x86_64/sublime-text.repo
sudo yum install sublime-text
