You can do worse than pip and virtualenv, yes, but I wouldn't call pip the cream of the crop by any means. NPM is way easier to use for starters, and Go, Rust and Nim go one step beyond NPM by compiling language dependencies down to a single binary file which can be shipped to users. It's very succinctly done.

Python really needs to step up the game to stay ahead of up and coming languages like Nim, which looks like this:

    import rdstdin, strutils

    let
      time24 = readLineFromStdin("Enter a 24-hour time: ").split(':').map(parseInt)
      hours24 = time24[0]
      minutes24 = time24[1]
      flights: array[8, tuple[since: int,
                              depart: string,
                              arrive: string]] = [(480, "8:00 a.m.", "10:16 a.m."),
                                                  (583, "9:43 a.m.", "11:52 a.m."),
                                                  (679, "11:19 a.m.", "1:31 p.m."),
                                                  (767, "12:47 p.m.", "3:00 p.m."),
                                                  (840, "2:00 p.m.", "4:08 p.m."),
                                                  (945, "3:45 p.m.", "5:55 p.m."),
                                                  (1140, "7:00 p.m.", "9:20 p.m."),
                                                  (1305, "9:45 p.m.", "11:58 p.m.")]

    proc minutesSinceMidnight(hours: int = hours24, minutes: int = minutes24): int =
      hours * 60 + minutes

    proc cmpFlights(m = minutesSinceMidnight()): seq[int] =
      result = newSeq[int](flights.len)
      for i in 0 .. <flights.len:
        result[i] = abs(m - flights[i].since)

    proc getClosest(): int =
      for k,v in cmpFlights():
        if v == cmpFlights().min: return k

    echo "Closest departure time is ", flights[getClosest()].depart,
      ", arriving at ", flights[getClosest()].arrive

And performs like this:

And the person in security hat now says: so how do you deal with library upgrades? If you need to go back to original app developers to provide you with a new version just to update one library, then you've got a problem.

Rust gives you the option to dynamically link, and I expect Nim does as well. As for Go, I believe dynamic linking is somewhere on their roadmap, though I don't know how high of a priority it is.
