The "think of tuples like a struct in C" explanation immediately
reminded me that ...

we change the docs and ecosystem to avoid the assumption that Python

Good question. My version was going to be that if you are dealing with
tuples of mixed data like (name, age, shoesize), inserting something or
sorting, in the way a list can, would confuse your code. A list, you
almost always iterate over, to do the same thing with each member, and
that only works if they are the same type of thing.
Then I realised David Beazley had explained this (but better), starting
in the Tuples section of his "Python Essential Reference". With
permission, this could perhaps be adopted wherever it best fits in the
documentation.

This looks like an issue to be addressed at PEP-8 since it looks like
a styling issue.
I haven't seen any other recommendations there on how to use a certain
data structure, though.

It's definitely something that should be put in some
documentation, probably at the point when people have learned
enough to be designing their own programs where this issue comes
up -- before they're wizards but well after they have learned the
semantic differences between lists and tuples.

Hello there!
I've stumbled upon this discussion on python-dev about
what the choice between using a list or a tuple is all
about in 2003:
1.
https://mail.python.org/pipermail/python-dev/2003-March/033962.html
2.
https://mail.python.org/pipermail/python-dev/2003-March/034029.html
There's a vague comment about it on python documentation
but afaik there the discussion hasn't made into any PEPs.
Is there an understanding about it?
Think of tuples like a struct in C, lists like an array.
That's just out of Guido's head so I don't think we have ever
bothered to write it down somewhere as an important
distinction of the initial design that should be emphasized.
