Pull random results from a database? - python-3.x

Question

I have been coding in Python for a 2 months or so, but I mostly ask for help from a more experienced friend when I run in to these kinds of issues. I should also, before I begin, specify that I use Python solely for a personal project; any questions I ask will relate to each other through that.
With those two things out of the way, I have a database of weaponry items that I created using the following script, made in Python 3.X:
#Start by making a list of every material, weapontype, and upgrade.
Materials=("Unobtanium","IvorySilk","BoneLeather","CottonWood","Tin","Copper","Bronze","Gold","Cobalt","Tungsten")
WeaponTypes=("Knife","Sword","Greatsword","Polearm","Battlestaff","Claw","Cane","Wand","Talis","Slicer","Rod","Bow","Crossbow","Handbow","Pistol","Mechgun","Rifle","Shotgun")
Upgrades=("0","1","2","3","4","5","6","7","8","9","10")
ForgeWInputs=[]
#Go through every material...
for m in Materials:
#And in each material, go through every weapontype...
for w in WeaponTypes:
#And in every weapontype, go through each upgrade...
for u in Upgrades:
ForgeWInputs.append((m,w,u))
#We now have a list "ForgeWInputs", which contains the 3-element list needed to
#Forge any weapon. For example...

def ForgeW(Material,WeaponType,UpgradeLevel):
"""The ForgeW function Forges a Weapon from its base components into a lethal tool."""
#Get the appropriate material stats...
OrePD=MAT[Material+"PD"]
OreMD=MAT[Material+"MD"]
OreAC=MAT[Material+"AC"]
#And weapon type stats...
SmithPD=WEP[WeaponType+"PD"]
SmithMD=WEP[WeaponType+"MD"]
SmithAC=WEP[WeaponType+"AC"]
#And apply the upgrade...
UpgradePD=UP[UpgradeLevel+"PD"]

#Then, add them all together.

ProductAC=(OreAC*SmithAC)*UpgradeAC
return(ProductPD,ProductMD,ProductAC)
#Recall that ForgeW simply needs its three inputs, which we have a list of. So, let's make our
#database of weapon information.
OmniWeapData={}
#Go through every set of inputs we have...
for Inputs in ForgeWInputs:
#And create a key in the dictionary by combining their three names. Then, set that
#key equal to whatever ForgeW returns when those three inputs are put in.
OmniWeapData[Inputs[0]+Inputs[1]+Inputs[2]] = ForgeW(Inputs[0],Inputs[1],Inputs[2])
I would like to refer to the database created by this code and pull out weapons at random, and frankly I have no idea how. As an example of what I would like to do...
Well, hum. The code in question should spit out a certain number of results based on the complete products of the ForgeW function - if I specify, either within the code or through an input, that I would like 3 outputs, it might output a GoldKnife0, a TinPolearm5, and a CobaltGreatsword10. If I were to run the code again, it should dispense new equipment - not the same three every time.
I apologize if this is too much or too little data - it's my first time asking a question here.

Answer 1

"Take this... it may help you on your quest."
There is a library called random with a method called choice().
e.g.
import random
random.choice([1,2,3])
>>> 2
It sounds like you need one item from Materials, one item from WeaponTypes, and one from Upgrades.
Also, rarely is there ever a need for a triple nested FOR statement. This should get you started.
