What does the command 'pip list' accomplish?

The command 'pip list' is used to display a list of all the packages that have been installed in the current Python environment. This includes all libraries and their specific versions, providing a snapshot of the available dependencies for the project being worked on.

For developers, this is particularly useful when managing project dependencies, ensuring that the correct packages are installed, and verifying the versions to avoid conflicts. This command helps streamline the process of checking the environment setup, especially when working with virtual environments or preparing for package updates or installations.

The other options relate to actions not performed by 'pip list': installing or uninstalling specific packages and checking their individual statuses are handled by different commands, such as 'pip install' for installation and 'pip uninstall' for removal. Therefore, 'pip list' distinctly serves the function of listing installed packages.
