can you call a function from a list?

[KEYS]

What i am trying to do:
create a inventory item that uses a function.
The code doesn't work but i will include it as it shows the function i am trying to call on as a list item.

def hall():
    inv=[]
    name=''
    name=input('enter name')
    print('you found an item')
    inv+=trophy(name)
    return name,inv

def show(inv):
        print(inv)

def trophy(name):
  sym='.'
  for i in range(1, len(name)+5, 1):
        print (sym, end="")
  print("\n.."+str(name)+"..")
  for i in range(1, len(name)+5, 1):
        print (sym, end="")

def main():
        name,inv=hall()
        show(inv)
        trophy(name)
main()
