Using multiple versions of Python with Navigator¶ With Navigator you can have different versions of Python on your computer and easily switch between them by keeping them in different environments. To use a different version of Python than the one you are currently using, set up a new environment: In Navigator, click the Environments tab, then click the Create button. The Create new environment dialog box appears. In the Environment name field, type a descriptive name for your environment. In the Packages list select “Python” and in the Python version list select the version you want to use. Click the Create button. Navigator creates the new environment and activates it, as shown by the highlighted green bar. All actions take place in the active environment.
