# Solved: tuple to list

Sure, I am more than ready to write your Haskell Tuple to List tutorial. Here it is:

Tuples are an essential aspect of the Haskell programming language. They provide a simple way to store multiple values together in one structure, but unlike lists, these values can all be of different types. However, sometimes you may find that a tuple isn’t the best structure for your needs, and you’d instead like to convert it into a list. This article will dive deep into how to transform a tuple into a list in Haskell.

A tuple-to-list transformation can be a handy operation in Haskell but it requires a critical understanding of both list and tuple features in Haskell. With that out of the way, let’s dive into the solution.

```tupleToList :: (a, a) -> [a]
tupleToList (x, y) = [x, y]
```

Above is a simple Haskell function that takes a tuple (x, y) and outputs it as a list [x, y]. This function follows the standard Haskell syntax for function definition. It includes the function name (tupleToList), the function parameters ((x, y)), the return assignment (=), and the returned list ([x, y]).

Haskell’s list is an homogeneous data structure, which means that every element in the list must be of the same type. In contrast, a tuple is a heterogeneous data structure, which means that a tuple can contain multiple elements of different types.

A key aspect of lists in Haskell is that they are recursive data structures. A list can be defined as an empty list or a combination of an element and a list. This recursive definition makes lists very convenient for recursive algorithm design.
