I asked a question because I assumed that I might not know something about it, since C# has Tuple<T1, T2> generic class just for that and if it would be just that, Python would have nothing on C# in that regard. But your comment is exactly what I was thinking about.
So, is there something else in Python that is not present in C#?
I doubt it, other than syntactic sugar, which makes tuples really easy to use, like destructuring and construction. I.e. in Python, if you have a function that returns a tuple:
a, b = f(xxx)
To create a tuple you just do (a, b). In Haskell, you get some other benefits, like tuples being functors (i.e. "things that can be mapped over"):
map show ("tuple", 5) == ("tuple", "5")
P.S. Not a Python expert, but I think tuples might be enumerable in Python, which works because Python is dynamically typed.
There is also a variant of a tuple which assigns names to its positions - it's also iterable. They are also allowed to have any length. Other than that, I'm not aware of any superpowers of Python tuples.
