[docs] [issue14840] Tutorial: Add a bit on the difference between tuples and lists

[Zachary Ware]

New submission from Zachary Ware <zachary.ware at gmail.com>:

I was looking through the documentation source files for things I might be able to fix, and stumbled across "XXX Add a bit on the difference between tuples and lists." in Doc\tutorial\datastructures.rst. So I took a stab at adding some prose to address that comment, reproduced here:

"""
Though tuples may seem very similar to lists, their immutability makes them
ideal for fundamentally different usage.  In typical usage, tuples are a
heterogenous structure, whereas lists are a homogenous sequence.  This tends to
mean that, in general, tuples are used as a cohesive unit while lists are used
one member at a time.
"""

Have I missed anything important (like the whole point) or is there anything I could phrase better?

Should this be applied to the tutorials of previous versions?
