In the AWS CloudShell, you might not have direct access to upgrade Python, but you can still manage Python versions using tools like pyenv.

Here’s a step-by-step guide:

  1. Check Current Python Version:
    Open a terminal in AWS CloudShell and check the current Python version by typing:
   python --version

This will give you an idea of the current version.

  1. Install pyenv:
    We will use pyenv to manage different Python versions. Install it by running the following commands:
   curl https://pyenv.run | bash

After the installation is complete, restart your shell or run:

   exec $SHELL
  1. Install Dependencies:
    Ensure that you have the required dependencies for building Python versions. On AWS CloudShell, you might need to install these:
   sudo yum install -y gcc zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel tk-devel libffi-devel
  1. Install Python Version:
    Use pyenv to install a specific Python version. For example, to install Python 3.8.12:
   pyenv install 3.8.12
  1. Set Global Python Version:
    Set the newly installed Python version as the global version:
   pyenv global 3.8.12
  1. Verify the Upgrade:
    Check if the Python version has been upgraded successfully:
   python --version

It should now display the version you installed.

Remember, in AWS CloudShell, you might need to re-run the pyenv global command every time you start a new session, as CloudShell doesn’t persist the environment between sessions.

This example assumes you have the necessary permissions to install software and dependencies. If not, you may need to contact your AWS administrator.
