to build and install Python, check its [README](https://github.com/yyuu/pyenv/tree/master/plugins/python-build)
for more information about build options and the [common build problems](https://github.com/pyenv/pyenv/wiki/Common-build-problems) wiki page for any issues encountered during installation of python versions.
## Using multiple versions of Python
A common request for Python is being able to use the `python2` and `python3` commands without needing to switch version.
This can be achieved by setting multiple versions of Python, for example with
```
asdf global 3.6.2 2.7.13
```
This feature is experimental but should be working well enough for most use cases.
