<div>The Pragmatic Programming Erlang says:</div>
<div>1) Suppose you want to group a fixed number of items into a single entity.For this you'd use a tuple.</div>
<div>2) We use lists to store variable numbers of things.</div>
<div> </div>
<div>However, we know that variables in Erlang are in essence invariable. So what is the difference between tuple and list ?</div>

<div>Thanks in advance.</div>
