Many open-source developers are committing to several projects, developing package (for Python). A fraction of developers might need funds for the continuing development of several projects and to pursue contributing. Sadly, there is no direct short way for donors to fund python package developers. There is no particular function in the python package installer(pip) and the site.
A command-line argument for listing the funding pages of package developer for packages installed by them (global or pyenv), will help donors to reach such developers easily. The funding page can be the GitHub sponsor page, or PayPal redirect (control of the developer)
Similar implementations include the "npm fund" command. This command retrieves information on how to fund the dependencies of a given project, released 4-5 months ago which has gained momentum.
