## Creating a Python sandbox
### Create the virtual environment
```sh
virtualenv -p python3 ~/myenv
```
The option`-p` selects the Python interpreter to use, e.g.,
`--python=python2.5` will use the python2.5 interpreter to create the new
environment. The default is the python2 interpreter on your path.
## Export Anaconda environment
```sh
source activate env-name
conda env export | grep -v "^prefix: " > environment.yml
```
