Ok so lets say i have this code:

var/sellable
var/sellprice
var/buyprice
obj
   sword
     icon = 'sword.dmi'
     sellable = 1
     sellprice = 190
   shield
     icon = 'shield.dmi'
     sellable = 1
     sellprice = 180
   bag
     icon = 'bag.dmi'
     sellable = 1
     sellprice = 300
   shopkeeper
     icon = 'shopkeeper.dmi'
     icon_state = "normal_s"
obj/verb
   shopkeeper
       buy() // do i put anything in the parenthesis?
       switch(input("Choose what you wish to buy","?")in list("Sword(200)","Shield(190)","bag(400)"))

How would i know what they picked there...and:
       sell()
       switch(input("Choose what you wish to sell","Sell?") if usr.inventory=sword  in list("Sword(200)"))

How would i get a variable to list every obj with sellable 1 in this list?

sorry about the bad coding, help me with variable setting aswell? Thanks, i just started coding and i need alot of help

I like to use an item subtype for any inventory items. Then you can just loop through /objs of that type and add them to the list. The way you're currently doing it seems to me like it's going to cause problems (multiple item procedure like Get() or Drop(), or overriding such procs for /objs that aren't items).

obj/item
  var/price

  rubber_ball
    price=2
  super_sword_of_deathly_doom
    price=42000

mob/verb/see_sellable_items()
  var/list/sellable=new
  for(var/obj/item/I in src)
    sellable+=I     // Fill the list.
  
  for(var/obj/item/sellable_item in sellable)
    src << "[sellable_item] will sell for [sellable_item.price]."
