Shorten the mini Christmas light strand
I remember those lights from when I was a child, long ago. The obvious way to wire multiple lights is in parallel. This will allow them to be quite independent: if one blew then the others would not be affected and you could take out unwanted ones or shorten the chain easily.  The problem with this obvious solution is that a small, low power bulb running at 100V would require a very thin filament and would be fragile with a short life.  The next most obvious solution would be low voltage bulbs and a transformer.  The third solution is to wire low voltage bulbs in series.  This has disadvantages but it is cheap.  One disadvantage is that if one bulb blows then all go out.  So, the bulbs are usually designed to short when they fail.  The others stay on but run a bit too hot and bright.  As more fail, there is a danger of runaway failure, so there is usually a fuse bulb that will break the circuit when it fails.  This is normally distinguished in some way; I remember a white coating around half the bulb and it is usually one nearest the supply.  Do not remove this bulb.
Your 34A figure is very wrong.  If you were drawing 34A at 100V then that would be 3400W which would be blinding and very hot in a typical room in a house.  P = I V so the actual current should be 0.408A.  Let's forget the .008.  100 identical in series connected to 100V will get 1V each. Since the current is 0.4A, we can deduce from V = I R that the resistance of each bulb is 2.5 Ohm.  So, you want 2.5 Ohm per removed bulb.  You are removing 82 bulbs so I calculate you need 205 Ohm.  With 63 Ohm, they will run very bright and hot and blow soon. Note that even if you get it right, you will use the same power as the full set and generate as much heat.  That resistor will get as hot as the 82 bulbs it replaced. Remember, don't omit the fuse bulb.
I have assumed a single strand of 100 bulbs. If it is two strands of 50 then the figures will be different.  Obviously, just detach one strand entirely.  I won't do those calculations as I don't suggest that you do this.
Although this is an interesting mental exercise, I don't suggest that you do it.  Buy a new set of LED lights. These will use a lot less power and run a lot cooler.  You could ask another question on how to shorten one of these sets but, since they use so much less power and run cooler, you may as well just hide the unwanted lights.  If you run the set for long then it might pay itself in reduced utility bills.  If it avoids a house fire then the saving will be even greater.
