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 Technical Account Manager.

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

   template_version: 2.0.0

2. 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">
   

3. In the requirements.txt file:

   1. Replace cloudshell-core with cloudshell-logging.
   2. Update the rest of the CloudShell packages to the latest versions.

4. In every .py file in the project:

   1. Update the code syntax to Python 3 format.

   2. 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.
