Expected str instance, int found. How do I change an int to str to make this code work?

I'm trying to write code that analyses a sentence that contains multiple words and no punctuation. I need it to identify individual words in the sentence that is entered and store them in a list. My example sentence is 'ask not what your country can do for you ask what you can do for your country. I then need the original position of the word to be written to a text file. This is my current code with parts taken from other questions I've found but I just can't get it to work

myFile = open("cat2numbers.txt", "wt")   
list = []  # An empty list 
sentence = ""  # Sentence is equal to the sentence that will be entered

print("Writing to the file: ", myFile) # Telling the user what file they will be writing to 
sentence = input("Please enter a sentence without punctuation ") # Asking the user to enter a sentenc
sentence = sentence.lower() # Turns everything entered into lower case
words = sentence.split() # Splitting the sentence into single words
positions = [words.index(word) + 1 for word in words]
for i in range(1,9):
    s = repr(i)
    print("The positions are being written to the file")
    d = ', '.join(positions) 
    myFile.write(positions) # write the places to myFile
    myFile.write("\n")
    myFile.close() # closes myFile
    print("The positions are now in the file")

The error I've been getting is TypeError: sequence item 0: expected str instance, int found. Could someone please help me, it would be much appreciated

The error stems from .join due to the fact you're joining ints on strings.

So the simple fix would be using:

d = ", ".join(map(str, positions))

which maps the str function on all the elements of the positions list and turns them to strings before joining.

That won't solve all your problems, though. You have used a for loop for some reason, in which you .close the file after writing. In consequent iterations you'll get an error for attempting to write to a file that has been closed.

There's other things, list = [] is unnecessary and, using the name list should be avoided; the initialization of sentence is unnecessary too, you don't need to initialize like that. Additionally, if you want to ask for 8 sentences (the for loop), put your loop before doing your work.

All in all, try something like this:

with open("cat2numbers.txt", "wt") as f:   
    print("Writing to the file: ", myFile) # Telling the user what file they will be writing to 
    for i in range(9):
        sentence = input("Please enter a sentence without punctuation ").lower() # Asking the user to enter a sentenc
        words = sentence.split() # Splitting the sentence into single words
        positions = [words.index(word) + 1 for word in words]
        f.write(", ".join(map(str, positions))) # write the places to myFile
        myFile.write("\n")
        print("The positions are now in the file")

this uses the with statement which handles closing the file for you, behind the scenes.

As I see it, in the for loop, you try to write into file, than close it, and than WRITE TO THE CLOSED FILE again. Couldn't this be the problem?
