Why Is This Basic If-Else Expression Failing?

This is my first post on the site. I am in my third week of coding class and have completed everything but this problem. We are using ZyBooks. I have completed everything but this participation exercise. It isn't graded; however, it is driving me nuts. We are asked to write an expression that will print "in high school" if the value of user_grade is between 9 and 12 (inclusive).
Sample output with input: 10 in high school
This is what I have so far: I apologize if I am posting this incorrectly.
user_grade = int(input())
if user_grade >= 9 <= 12:
print('in high school')
else:
print('not in high school')
The code passes all tests until it runs input: 13. Then I receive this error:
Output differs. See highlights below.

Expected output: not in high school

I think your order of operations in the if is slightly wrong. Do you mean the following:
if 9 <= user_grade <= 12:
Because right now you are checking:
- is 9 smaller or equal to user_grade AND
- is 9 smaller or equal to 12
If you enter 13 then the first check will be True. But as the second check is only comparing 9 and 12 it is always true. And therefore you are never testing if user_input is smaller or equal to 12.
Your condition is wrong. You should use:
if 9 <= user_grade <= 12:
print('in high school')
The order of the comparsion matters. user_grade >= 9 <= 12 means user grade is inferior or equals to 9 AND 9 is inferior or equals to 12.
Guess that it should more readable as follows:
def user_grade (input):
if input >= 9 and input <= 12:
print('in high school')
else:
print('not in high school')
user_grade(13)
The answer to the zybooks question is:
8 < user_grade < 13
