How to check multiple indexes at once?

So say i have a random list. If i want to check if the number at index 0 is either 0, 1, 2, 3, 4, 5, 6, 7 or 8. How would i go about doing that in a smart way? Obviously i could do an or statement for every action like so:

if list1[0] == 1 or list1[0] == 2 or list1[0] == 3 etc..
    print("something")

But surely there is a smart way of doing it?

I think the easiest way is to use a range, and check for inclusion in that, like this:

if list1[0] in range(1, 9):
    print("something")

The above code will check if list[0] is somewhere between 1 and 8, and will print "something" if it is

Yes but the problem is that the list is a variable, that dosens just contain numbers

For this case, the in operator will simply return False in the event that the object you're testing is not an int, so this solution should still work
