Python: Trouble sub scripting lists and accessing data in later print statement, what am I doing wrong?

This is a question that I have been tasked with, I am fairly new to Python so I am struggling a bit enter image description here

(I only need to do 8 horses)

This is my code so far:

horse_info = [['A',11,12],['B',17,7],['C',14,28],['D',15,10],['E',18,30],['F',13,3],['G',16,18],['H',12,23]]

max_h = int(input('Maximum height: '))
max_a = int(input('Maximum age: '))

for i in range(len(horse_info)):
    if int(max_h) <= horse_info[i[i]] and int(max_a) <= horse_info[i[i]]:
        print('yes')

But I am getting this error:

> Traceback (most recent call last):   File
> "/Users/MattDaGama/Documents/Q43.py", line 7, in <module>
>     if int(max_h) <= horse_info[i[i]] and int(max_a) <= horse_info[i[i]]: TypeError: 'int' object is not subscriptable

Would appreciate any help :)

EDIT:

I think I have figured out the if statement but I am not sure how to make the print statement.

horse_info = [['A',11,12],['B',17,7],['C',14,28],['D',15,10],['E',18,30],['F',13,3],['G',16,18],['H',12,23]]

max_h = int(input('Maximum height: '))
max_a = int(input('Maximum age: '))

for i in range(len(horse_info)
    if int(max_h) <= horse_info[i][1] and int(max_a) <= horse_info[i][2]:
        print(horse_info[i][1,2,3])

When I try and run the code it just doesn't print anything.

The problem is that when you iterate over a range, the i is an integer. The integer data type is not subscriptable (i.e. you can't do the same thing you can with a list[i] for instance to jump to the index of a list. Ints don't have indexes.

So as a starting place:

if int(max_h) <= horse_info[i[i]] and int(max_a) <= horse_info[i[i]]:

Should be -

if int(max_h) <= horse_info[i][1] and int(max_a) <= horse_info[i][2]:

Assuming horse_info[0][1] = 11 and horse_info[0][2] = 12 based on the variable declaration in the question, (i.e. horse_info = [['A',11,12], ... ]

You have a list of lists, and i is the index of the outer list you want to work with, and the second set of [] are the index of the value you want to work with
