Python Compilation

---

To have another Python versions for the Linux Users without impacting the operating system, the best approach is to install Python locally in the user's home directory. This method avoids requiring root/sudo access and does not alter the system-wide Python installation.

To install Python (e.g.: 3.9.25) locally for a user without sudo access, including the pip module, follow these steps:

alexolinux

#!/bin/bash

#https://hub.docker.com/r/portainer/agent
AGENT_VERSION="2.33.3-alpine"

# Check if the script is being run as root.
if [ "$(id -u)" -eq 0 ]; then
  echo "This script should not be run as root. Run it as a non-root user."
  exit 1
fi
