Python Tuples are Immutable, Except When They
WebAug 27, 2024 · To modify an element at index “i” of a tuple, we will create two slices of the original tuple. The first slice will contain elements from index 0 to i-1 of the original tuple. The second slice will contain elements from index “i+1” to last. After that, we will update the element at index “i” by inserting the new value at the position as follows. WebSep 28, 2024 · To use tuples in a project that targets .NET Framework 4.6.2 or earlier, add the NuGet package System.ValueTuple to the project. You can define tuples with an arbitrary large number of elements: C# var t = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26); Console.WriteLine (t.Item26); // output: 26 WebFeb 5, 2024 · This is an interesting corner case: a tuple (which should be immutable) that contains a mutable list cannot be hashed.
