What is wrong in the syntax of if statement line 17 , I am stuck at this SyntaxError

I am trying to solve the practical problem of chapter 5 Automate the Boring Stuff. I am stuck here, I tried everything but again and again, it shows SyntaxError on line 17, I checked on the syntax of if statement and I think it is perfectly fine, Can anyone help me here?

def displayInventory(inventory):
    print("Inventory:")
    total=0
    for k,v in inventory.items():


        print(str(v)+" "+str(k))
        total+=int(v)

    print("Total number of itmes: "+str(total))
stuff = {'rope': 1, 'torch': 6, 'gold coin': 42, 'dagger': 1, 'arrow': 12}

displayInventory(stuff)

def addToInventory(inventory, addedItems):
    for i in range(len(addedItems):
        if str(addedItems[i]) in inventory :
            inventory[str(addedItems[i])] += 1
        else:
            inventory.setdefault(addedItems[i],1)


inv = {'gold coin': 42, 'rope': 1}
dragonLoot = ['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby']

addToInventory(inv,dragonLoot)s

displayInventory(inv)
