Why is my list not being stored in hold.txt?

Question

My problem is my list(lst) is not storing in the file. WONDERFUL COMMUNITY YOU HAVE. I am new to the site so please be aware of that in the comments. The following is my code I was able to store it long ago but there were problems so I undid it and for some reason, in my head, I CANNOT REMEMBER what I did to store it!

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
    if answered == False:
         print("You typed days of week wrong! Try Again!")
def listToString(): 
  if 0 < 2:
    test = open('hold.txt', 'a')
    print(test.write(lst + '\n'))
    test.close()
    return listToString

'a+' does not work!! in repl.it I have tried many things that would be a waste to mention just really trust me I have a stroke explaining. But when I do put lst into the file i want it to be spaced out on each line so for each item i would like it on a new line but for not just storing 1 item. I am new to this site. Also does any one wanna tell me why my code keeps giving me the output of what appears to be the size of 1 item in a list that I write to my file

Answer 1

Below points need changes:

• Need to convert list to str
• Call listToString() method

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
    if answered == False:
         print("You typed days of week wrong! Try Again!")
def listToString(): 
  if 0 < 2:
    test = open('hold.txt', 'a')
    # and list is not able to con-cat with str, so need to convert that too
    test.write(str(lst) + '\n')
    test.close()
    return listToString

# you need to call the method to execute the method code
listToString()

Answer 2

Did you mean to call your function:

def listToString(lst): 
    with open('hold.txt', 'a') as test:
        test.write(str(lst) + '\n')

listToString(lst)

Answer 3

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 evaluated after reviewing all words, if True is not set, prompts user again and let's them know that their answer is not valid
    if answered == False:
         print("You typed days of week wrong! Try Again!")

def listToString(): 
    with open('hold.txt', 'w') as f:
    for day in lst: 
        f.write(day + '\n')

listToString()

It is also advised to use with to open and close your files. You can find more information about it here. I printed every day entry on a separate line, if you want to just print your list on one line you can change this back and add str(lst).

Answer 4

I checked your code. Just so you know what quamrana said is necessary, I ran the code and think there's two things you might be failing on:

def listToString(): 
  if 0 < 2:
    test = open('hold.txt', 'a')
    test.writelines(line+'\n' for line in lst)
    test.close()
    return

if __name__=="__main__":
  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
      if answered == False:
          print("You typed days of week wrong! Try Again!")

1. If you call the function just as it is, then it will give you an error since lst is a list and '\n' is a string, therefore, what i propose is using the writelines method that writes every element on the list and adds a '\n' at the end of it
2. I think, you might want to pass lst as a parameter and not using a global variable Note: I formatted the file, for it to be easier to read
