Writing one per line and closing the file

The code writes the tags to tags.txt, one per line, then reads the file back and prints its content exactly as it is between two --- lines. Fill in the two blanks so that every line ends with a newline and the file is closed after writing.

Code with blanks

tags = ["cat", "dog", "art"]
f = open("tags.txt", "w")
for tag in tags:
    f.write(____)
f.____

f2 = open("tags.txt", "r")
text = f2.read()
f2.close()
print("---")
print(text, end="")
print("---")
