I find that I frequently (many times daily) have to send files as email attachments. Depending on the task, the files can be located in a half-dozen or so places on the Windows file system. I found myself browsing (from Outlook's "Attach File" function) to my Documents, Downloads, Desktop, or one of several network drives for the file I just saved there a few seconds ago.
When installing a Python 3 package with Pip, if the package to be installed calls for a dependency that is outdated or otherwise not available, you can get a local copy of the module, change its dependency lists, then install it from the local source.
This will likely be no big deal for the Python wizards out there, but it was a pretty nice victory for me, so I thought I'd better share in case someone else has the same trouble.
