Install python 3.7, 3.6, 3.5, and 3.4 on BigSure with pyenv

This post is about installing python 3.5, 3.6, and 3.7 since my previous post only supports python 3.8 and 3.9.
Also, I have gotten some questions on installing python 3.5 and 3.6.

In addition, I really need to install them on my BigSur lol.

Install python 3.7.3

I tried to install 3.7.6, 3.7.7, 3.7.8, and 3.7.9, but couldn't install them. Only 3.7.3 worked with the following.
