Some package managers, including pip, use PyPI as the default source for packages and their dependencies. [6] [7] As of 6 May 2024, more than 530,000 Python packages are available. PyPI primarily hosts Python packages in the form of source archives, called "sdists", or of "wheels" [8] that may contain binary modules from a compiled language.

The package can also be provided as source code to be compiled on the system.
Some distributions like Debian tend to separate tools into different packages – usually stable release, development release, documentation and debug. Also counting the source package number varies. For debian and rpm based entries it is just the base to produce binary packages, so the total number of packages is the number of binary packages.
Summarising the situation in 2013, Richard Stallman identified nine aspects which generally apply to being a GNU package, [1] but he noted that exceptions and flexibility are possible when there are good reasons: [2] The package should say that it is a GNU package. It should be distributed via ftp.gnu.org, or another site offering access to ...
