In-built Python Version Manager (PVM) and Package Manager

[edward-sam]

Feature or enhancement

Proposal:

Description:

Please consider adding an in-built Python Version Manager (PVM) similar to existing tools like fnm (Fast Node Manager. The PVM should offer the following subcommands:

• pvm list or pvm ls: Lists all locally installed Python versions.
• pvm list-remote or pvm ls-remote: Lists all available Python versions for download, including alpha and beta versions.
• pvm install <version>: Installs the specified Python version.
• pvm use <version>: Sets a specific Python version for the current session.
• pvm default <version>: Sets a default Python version globally.
• pvm current: Displays the currently active Python version.
• pvm uninstall <version>: Uninstalls the specified Python version.
• pvm help: Displays help information for PVM commands.

Additionally, consider adding a Python package manager similar to Node's package.json system. Python could have a command like pip init or pip init -y to initialize a new project with package dependencies.

Additional Features:

• Hot Reloading & Watch Mode:
  • Add support for py --hot main.py to provide hot-reloading of the Python script.
  • Add py --watch main.py to watch for file changes and automatically restart the script.

These enhancements would greatly improve Python's usability and developer experience.

Expected Benefits:

• Simplified Python version management with comprehensive subcommands.
• Streamlined package initialization and management.
• Enhanced development workflow with hot-reloading and file-watching capabilities.

Hello!
Such a major feature should be widely discussed first. Please make a post at https://discuss.python.org/c/ideas/6.
Now I'm going to close it, we can re-open it later if needed.
