How to use `EquationsOfStateOfSolids` in Python?

It may be attempting for Pythonistas to use this package in Python, without writing too much code. Luckily, Julia provides such a feature.

First, install PyCall.jl, following their instructions. Notice on macOS, that if you want to install Python from pyenv, you may need to run
```
env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.6.9
```
in terminal to install your python, or else Julia will throw an
```
ImportError: No module named site
```
See this issue and another issue for details.
Install PyJulia in Python. Please see its official tutorial for instructions.
