Print Pattern Haskell at Molly Carmichael blog

Print Pattern Haskell. This chapter will cover some of haskell's cool syntactic constructs and we'll start with pattern matching. In some languages that support pattern matching, there is a feature that allows you to match against multiple patterns at once. Haskell has a simple, but tremendously useful, pattern matching facility that lets us do both of these things. You can combine the iteration and printing into a single function like this: Print takes a value of any type that's an instance of show (meaning that we know how to represent it as a string), calls show with that value to stringify it and then outputs that string to the terminal. A pattern lets us look inside a value. If you have a string that you want to print to the screen, you should use putstrln. If you have something other than a string that you want. Pattern matching consists of specifying patterns to which some data should conform. I am trying to print the elements of my list onto new lines, but i cant get it to work;
