How to properly structure "for scores less than 10 or greater than 90" within an if statem-CodePudding

I'm simply trying the following:

if score < 10 or > 90:
    print(f"Your score is {score}, you go together x and y.")

but it gives an error:

    if score < 10 or > 90:
                     ^
SyntaxError: invalid syntax

Would someone explain the reason behind it not liking > 90? Its type is integer. Instead of just looking at the solution I want to understand why.

if score < 10 or score > 90:
    # ...

You can, however, use comparison operator chaining to get the same condition (possibly more readable):

if not (10 <= score <= 90):
    # ...
