- Whats the difference between lists and tuples? - Stack Overflow
What are the differences between lists and tuples, and what are their respective advantages and disadvantages?
- python - What is a tuple useful for? - Stack Overflow
1 A tuple is useful for storing multiple values As you note a tuple is just like a list that is immutable - e g once created you cannot add remove swap elements One benefit of being immutable is that because the tuple is fixed size it allows the run-time to perform certain optimizations
- Returning multiple values from a C++ function - Stack Overflow
F 21: To return multiple “out” values, prefer returning a struct or tuple Reason A return value is self-documenting as an “output-only” value Note that C++ does have multiple return values, by convention of using a tuple (including pair), possibly with the extra convenience of tie or structured bindings (C++17) at the call site
- 如何理解和使用tuple？ - 知乎
tuple一般在中文中称为元组，或者说n元组。就是由n个元素组成的一种有序数据结构（当然n是不小于零的整数）。不同的编程语言对元组有不同实现，但既然标签打的Python，那就只谈和Python中的元组有关的。 Python对元组有语法支持，直接括号里写上用逗号分隔的值即可构造一个元组：
- c# - Return multiple values to a method caller - Stack Overflow
The tuple probably is the best option for readability Personally, I'm not keen on having anonymous types or property names like Item1 - although I guess destructuring does mitigate that The last example, in terms of source code, definitely looks the most like multiple return in languages with that as a native feature
- types - What are named tuples in Python? - Stack Overflow
Named tuple instances can be referenced using object-like variable dereferencing or the standard tuple syntax They can be used similarly to struct or other common record types, except that they are immutable They were added in Python 2 6 and Python 3 0, although there is a recipe for implementation in Python 2 4
- Python List of Tuples (Find value with key + check if exist)
This reimplements a dict lookup On large Lists of Tuples it will be slow as it requires cycling through each Tuple for matches whereas Dicts are backed by a hash table
