What is wrong with this code (Password validation from code coach)

Question

import re

user=input("")
length=7

pattern = r"[A-Z][A-Z][0-9]['!','@','#','

Answer 1

Even if you do not know all the nuances of creating a template, you can still write code, just use several instead of one template. ☺️

Answer 2

You wrote pattern so that the first two characters must always be in uppercase, 3rd digit, 4th one of the specified characters.

Answer 3

You do not understand, you have a fixed pattern with an unchanging sequence of characters.

Answer 4

I fixed it and still this code is not working
from[A-Z][A-Z] to [A-Z][a-z]
