can you call a function from a list?

[KEYS]

I have no idea why or what but I can address this 'adding to list' / 'getting entire function output' part:

>>> def my_func():
...     print('Hello world')
...
>>> list_ = []
>>> list_.append(my_func)
>>> list_[0]()
Hello world

This looks like what i may need, but i am getting TypeError: 'builtin_function_or_method' object is not subscriptable

def hall():

    name=''
    inv=[]
    inv.append[trophy(name)]
    name=input('enter name')
    print('you found an item')

    return name,inv

def show(name,inv):
        print(inv[0])
        
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(name,inv)
        trophy(name)
main()
