Python text for loop list index out of range [duplicate]

I am trying to write a code that prints hello and a different number on each line. Sample output would look like this:

hi 21

hi 22

hi 23

etc. However I am getting a list index out of range error for my for loop.

Here is my code:

    number = [21,22,23]
    for x in number:
        print('hi',number[x],'\n')

I am new to programming and any help would be greatly appreciated!
