How do I stop text_file overriding previously written lines?

Question

I've got my code, I'm trying to make a mood diary of some sorts, it works fine, but when I go back to the script and run it again to add another entry, it just overrides my last entry, how could i prevent this?

import datetime

date = datetime.datetime.now()
print('My Mood Diary:')
mood = input('How are you feeling today? ')
text_file = open("Diary.txt", "w")
text_file.write('Date:\n')
text_file.write(date.strftime("%Y-%m-%d @ %H:%M:%S\nEntry:\n"))
text_file.write(mood)
text_file.write('\n')
text_file.close()

Open it in append mode: `text_file = open("Diary.txt", "a")` — Thierry Lathuille, Aug 09 '20 at 13:34

I think the title of the duplicate question definitely is not beginner friendly. Could it be made better? — Vishesh Mangla, Aug 09 '20 at 13:36

Use append:

text_file = open("Diary.txt", "a")
                               ^
