Migrating Shells to Python 3

In this article, we’ll explain the general process for upgrading a Python 2-based shell to Python 3.

Note: Quali is currently working on updating all Quali-certified Python 2 shells to Python 3, so if you need a Python 3 version of a Quali-certified shell, please contact your Quali Customer Success representative.

1) Open the shelldefinition.yaml file and promote the shell version. For example:

template_version: 2.0.0

3) Open the drivermetadata.xml file and add the PythonVersion=”3” tag:

<Driver Description="Describe the purpose of your CloudShell shell" MainClass="driver.CloudService2Driver" Name="CloudService2Driver" Version="1.0.0" PythonVersion="3">

4) In the requirements.txt file:

     a. Replace cloudshell-core with cloudshell-logging.

     b. Update the rest of the CloudShell packages to the latest versions.

5) In every .py file in the project:

     a. Update the code syntax to Python 3 format.

     b. Update the import of cloudshell-core to cloudshell-logging (no need to update the code).

from cloudshell.logging.qs_logger import get_qs_logger

5) Make sure all non-CloudShell packages support Python 3.

6) Pack and install the shell on CloudShell.
