I do a lot of building, so package errors cause the most friction. In particular, when working with pip, the ModuleNotFoundError: after all package names can be confusing / unexpected and not correspond to the module name (even worse, there may be a package with the same module name that has nothing to do with that module!), so figuring out which package provides a module with that name usually involves time-consuming research to pinpoint the exact required package.

For missing libraries dnf provides*/ is my life-saver, surely there must be something similar for pip, the package manager for one of the most widely used languages in the world...
