What are the hooks for the submit event?

Question

Python

Hello. I'm wondering if there are any hooks that fire when submitting a form, except for admin_post and its variants?
If I understand correctly, admin_post only works for site admins?

Answer 1

Obviously, the reason for the slowdown is due to the opening and closing of base.txt, deleted.txt and good.txt files for each line from first.txt.
It should be something like this:

f2 = open("base.txt", encoding = 'utf-8')
d = open('deleted.txt', 'a', encoding = 'utf-8')
ffinal = open("good.txt",mode = 'a',encoding = 'utf-8')
f1 = open("first.txt",mode = 'r',encoding = 'utf-8')
for line in f1:
   ...
f1.close()
ffinal.close()
d.close()
f2.close()
