# Python templates

Anaconda Enterprise templates environments are provided Python versions
2.7, 3.5, and 3.6.

In a running project session the Python 2.7 environment includes all of the
packages in the [Anaconda distribution for Python 2.7](/docs/getting-started/anaconda/release/1.x) *with a check mark* in
the **In Installer** column. The same is true for the [Python 3.5](/docs/getting-started/anaconda/release/2.x) and
[Python 3.6](/docs/getting-started/anaconda/release/4.x) environments.

Additional conda and pip packages can be added using the process described in
[Developing a project](../projects/dependencies).

For example, to upgrade to a newer version of Pandas and add the HvPlot
package, run the following in a terminal

```
anaconda-project add-packages pandas=0.25 hvplot

```

Python notebooks can be edited with any of the editors provided with Anaconda
Enterprise: Jupyter Notebooks, JupyterLab, or Apache Zeppelin. To change the
default editor for your Python project, click on it or select **View details**
from its menu in the list view. Then click **Settings** to select your
preferred editor. For more information, see [Working with projects](../projects/main).
