[erlang-questions] What's the difference between tuple and list ?

[Bengt Kleberg]

greetings,

it is as simple as it says. if you have a variable amount of things you 
store them in a list (ex: the number of people inside a room). if you 
have a fixed number of items you store them in a tuple. (ex: descriptive 
data about a person, like age and name).
