### Create a new environment:

To create the new environment for Python 3.x, in your terminal window or an Anaconda Prompt, run:

Example: env name 'py36'

```
conda create -n py36 python=3.6 anaconda
```

### Update/upgrade Python

You can update Python in the same branch or upgrade to a higher branch.

#### Update in Anaconda Prompt:

If you are in an environment with Python version 3.4.2, the following command updates Python to the latest version in the 3.4.x branch:

```
conda update python
```

#### Upgrade in Anaconda Prompt:

The following command upgrades Python to another branch from 3.4 to 3.6 by installing that version of Python:

```
conda install python=3.6
```
