For those that want to learn more about "one line filtering lists", they are an example of list comprehensions. In addition to filtering, you can use them to get a list of some property on objects, or perform some operation:
To add to this, the output of the range function is a generator which generates values on the fly as opposed to having them stored in memory all at once.
Furthermore, if you replace the square brackets of a list comprehension with curved brackets, you get a generator comprehension.

You can also make dictionary comprehensions.
A related concept is range:
Note that in Python 3, range is not a list but rather its own type. However, you can use it very similarly to a list.
To add to this, the output of the range function is a generator which generates values on the fly as opposed to having them stored in memory all at once.
