List Won't Write in Text File

[IILawrenceII]

import time
global list

list = [] #####This is not the final list, but a list where you add everything to be sorted


def add_to_list(): #####This should loop until you decide you are ready
        

	print("Artist: Album (or type \"done\" if you have finished the list)")
	add = input()

	if add == "done":
		finalize_list()

	else:
		list.append(add + "/n /n")
		add_to_list()


def finalize_list():

    list_sorted = list.sort() ####This list should be alphabetical
    list_final = str(list_sorted) ####This should convert the list to a string due to an earlier error
	
    file = open("LP_list.txt", "w+")
    file.write(list_final)
    file.close()
	
    print("List is now in the text file.")
    time.sleep(3)
	
    exit()



####Actual

add_to_list()

This code writes "None" (without the quotation marks) into the file.

My objective is to first write something, hit enter, append it to the list, then sort the list out alphabetically and then write it into a .txt file.
