pip installs Python packages into the current environment (global or virtualenv). Used for libraries your code imports.               
                                                                                                                                        
  pip install requests  # available to all scripts in this env                                                                          
                                                                                                                                        
  pipx installs Python CLI tools into isolated virtual environments, each getting its own. Used for standalone command-line             
  applications.                                                                                                                         
                                                                                                                                        
  pipx install black  # `black` command available globally, but its deps are isolated
                                                                                                                                        
  Key differences:

  Rule of thumb: If you run it as a command, use pipx. If you import it in code, use pip.
