I get what the difference is between a tuple and a list, but why would I ever care about the tuple's immuutability?
Because, from a purely pratical POV, only an immutable object can be used as kay in a dict.
<my-bad> s/kay/key/ </my-bad>
This is not true.
Chapter and verse, please ?
So you can use tuples for 'composed key'.
lists can be so used too. Just provide a hash.
Please show us an example, and let's see how useful and handy this is from a "purely practical POV" ?-)
