How can I write to the textfile with "while"?

while 1:
    text_file = open("write_it.txt", "w")
    word = input("Please add to a text file: ")

What else do I need to add to make my code ru开发者_StackOverflown properly?

This should work:

text_file = open("write_it.txt", "w")
while 1:
    word = input("Please add to a text file: ")
    if not word:
        break
    text_file.write(word)
text_file.close()

Not sure, but that open statement inside of the while couldn't be affecting its behaviour? Have you tried just moving it out of while loop?
