Dowloading package dependencies from locked down machine

[Andrew McLean]

At work my only Internet access is via a locked-down PC. The IT 
department are not willing to install Python on it [1]. Ideally I would 
download packages and their dependencies from PyPi using "pip download" 
at the command line. Any better solutions than downloading the package 
in a browser, finding its dependencies manually, downloading these and 
so on recursively?

My dream solution would be for PyPi to provide a link to a zip file that 
bundled up a package and its dependencies, but I realise that this is 
probably a very niche requirement.

[1] Apparently they think installing Python would be incompatible with 
their Cyber Essentials Plus security accreditation, although it's 
apparently fine to have Microsoft Office 365 with a build in VBA 
interpreter!
