- Whats the difference between lists and tuples? - Stack Overflow
The PEP 484 -- Type Hints says that the types of elements of a tuple can be individually typed; so that you can say Tuple[str, int, float]; but a list, with List typing class can take only one type parameter: List[str], which hints that the difference of the 2 really is that the former is heterogeneous, whereas the latter intrinsically homogeneous
- python - What is a tuple useful for? - Stack Overflow
A tuple is a good way to pack multiple values into that cookie without having to define a separate class to contain them I try to be judicious about this particular use, though If the cookies are used liberally throughout the code, it's better to create a class because it helps document their use
- How does tuple comparison work in Python? - Stack Overflow
Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i e the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on See Common Sequence Operations:
- types - What are named tuples in Python? - Stack Overflow
It's a specific subclass of a tuple that is programmatically created to your specification, with named fields and a fixed length This, for example, creates a subclass of tuple, and aside from being of fixed length (in this case, three), it can be used everywhere a tuple is used without breaking This is known as Liskov substitutability
- python - Add another tuple to a tuple of tuples - Stack Overflow
Build another tuple-of-tuples out of another_choice, then concatenate: final_choices = (another_choice,) + my_choices Alternately, consider making my_choices a list-of-tuples instead of a tuple-of-tuples by using square brackets instead of parenthesis:
- parsing - Python casting Tuple [int, int] - Stack Overflow

- How can you iterate over the elements of an std::tuple?
The tuple need not be std::tuple, and instead may be anything that supports std::get and std::tuple_size; in particular, std::array and std::pair may be used; The tuple may be a reference type or cv-qualified; It has similar behavior as std::for_each, and returns the input UnaryFunction;
