This is a memo for myself, but for your reference.
Install "Homebrew" ↓ Install "pyenv" using "Homebrew" ↓ Install "Python" using "pyenv"

$ brew -v
Homebrew 2.2.2
Homebrew/homebrew-core (git revision d7286b; last commit 2020-01-01)
Install pyenv (a tool for building and managing multiple versions of Python environment in the same terminal) using Homebrew. pyenv's GitHub repository: https://github.com/pyenv
$ brew install pyenv
After the installation is complete, check the version with the following command.
$ pyenv -v
pyenv 1.2.13
pyenv settings: Added setting code to .bash_profile.
Execute the following command line by line (it looks like nothing is happening, but that's OK).
$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile
Install Python using pyenv.
First, execute the following command to check the version of Python that can be installed with pyenv.
$ pyenv install --list
#Python version that can install the execution result without the first alphabet
2.1.3
2.2.3
2.3.7

3.6.5
3.6.6
3.6.7

Of these, I installed the relatively new Python 3.6.5.
$ pyenv install 3.6.5
After the installation is complete, check the version of Python installed with the following command.
$ pyenv versions
system
* 3.6.5 (set by /Users/hoge/.pyenv/version)
Execute the following command to change the setting to use the version of Python installed above (otherwise this will continue to use the version of Python that is installed by default on your Mac).
$ pyenv global 3.6.5
Execute the following command to check the version of Python you are using.
$ Python --version
Python 3.6.5
Select Release version = Python 3.6.5 from the following site, download it, and install it according to the instructions.
Python 3.6.5 download page (official): https://www.python.org/downloads/release/python-365/
It seems that any file to download is for Windows, but unless you are particular about it, select Windows x86-64 executable installer.
When you open the downloaded file, there is a checkbox at the bottom of the screen that says ʻAdd Python 3.6 to PATH. Check this and click ʻInstall Now.
After the installation is complete, execute the following command at the command prompt (so-called black screen) to check the version.
$ Python --version
Python 3.6.5
If the message "'python' is not recognized ..." is displayed, you may have forgotten to check ʻAdd Python 3.6 to PATH when installing Python. In this case, reopen the first downloaded file, click ʻUninstall to delete it, and then install it again.

This is because openssl is not installed. In this case, if you install openssl as below and then install Python again, it will work (only for Mac, Windows is unconfirmed).
# 1.Install openssl.
$ brew install openssl
# 2.Changed the preferred SSL from LibreSSL to OpenSSL installed above.
$ echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
# 3.Exit the terminal and restart it. After that, check the version and OK when OpneSSL is displayed.
$ openssl version
OpenSSL 1.1.1d 10 Sep 2019
# 4.Reinstall Python.
$ pyenv install 3.6.5
