I am working on containment.
i saw teacher's note that has example of
"java" in "javascript" would give back True.
5 in [3, 4, 1] would give back False.
why is that?

Both strings and lists are iterable, so you can loop through their contents to check and evaluate various things. In a string, you would loop through the letters, in a list, the list items.
So if you were to check to see if the letters "java" were in the string "javascript", python would evaluate that as True because it is. But the letters have to be in the correct order. If you were to check for "jvaa" in "javascript", for example, it would return False because although the letters exist, they don't exist in that order.
With the list, you would check to see if the number 5 exists in the the list [3, 4, 1]. Since it does not, it would return False.
Hope this clears things up.
