How to do it...

1. Create an empty list:

        emptyList = []

2. Prepend an element to the list:

        prepend = 10 : []

3. Create a list of five integers:

        list5 = 1 : 2 : 3 : 4 : 5 : []

4. Create a list of integers from 1 to 10:

        list10 = [1..10]

5. Create an infinite list:

        infiniteList = [1..]

6. This is the head of a list:

        getHead = head [1..10]

7. This is the tail of a list:

        getTail = tail [1..10]

8. This is all but the last element:

        allbutlast = init [1..10]

9. Take 10 elements:

        take10 = take 10 [1..]

10. Drop 10 elements:

        drop10 = drop 10 [1..20]

11. Get n^th element:

        get1331th = [1..] !! 1331

12. Check if a value is the element of the list.

        is10element = elem 10 [1..10]

13. Do pattern matching on the list. Here we check whether the list is empty or not: ...
