[issue26074] Add a method to pip.. pip.require("package_name")

New submission from Blaize Rhodes: The idea is to add a method to pip that tries to import a package and if the import fails then try to download and install the package handling the UI. Yes, you can put the package as a dependency in your pip config for your code. This is intended for the

Xavier de Gaye added the comment: FWIW I have followed the idea of having _iterdir() yielding the DirEntry entry instead of the name in Serhiy's patch. There is a slight performance gain. Now _glob0() and _glob1() do return a list of directories when dironly is true but there is now another

[issue26077] Make slicing of immutable structures return a view instead of a copy
