I did a dummy python script on the rakefile

desc "Run Python with YAML import"
task :run_python do
  puts "Executing Python code..."
  python_code = <<~PYTHON
    import yaml
    import sys
    print("Python executing...", flush=True)
  PYTHON
  
  root_dir = File.expand_path('.')
  venv_python = File.join(root_dir, '.home', '.venv', 'bin', 'python3')
  
  puts "Using Python at: #{venv_python}"
  result = system venv_python, "-c", python_code
  if !result
    puts "Python command failed with exit code: #{$?.exitstatus}"
  end
end

It's working just fine! Thanks!
