days = ["sunday","monday", "tuesday", "wednesday", "thursday", "friday", "saturday"]
answered = False
while answered == False:
    userInput = input("What day of the week would you like to assign a event: ")
    lst = []
    input_words=userInput.lower().split()
    for word in input_words:
        if word in days:
            lst.append(word)
            print(word)
            # set answered to True boolean
            answered = True 
            print((lst))      
    #only evaulated after reviewing all words, if True is not set, prompts user again and let's them know that their answer is not valid also idk why above is not showing as a comment :(
    if answered == False:
         print("You typed days of week wrong! Try Again!")
def listToString(lst): 
  if 0 < 2:
    test = open('list.txt', 'w')
    print(test.write(lst))
    test.close()

So i'm asking user for input and must fit into days then store it in lst and then put it in a file list.txt except I don't want it to be a list i want it to be on seperate lines but it's not storing in my file for some reason which is quite annoying remember i dont want it to be a list when stored in file cause I can't really call on a item like that. first time using this site so go easy on me and leave down some suggestions :) have a good day

What I have tried:

I tried append and checked the file that I had and still nothing I typed was stored
