Tuple is a linear data structure which more or less behaves like a python list but with a really important difference, that a tuple is immutable . Immutable means that this structure can't be changed after it has been created, it can't be mutated if I may. Tuples being immutable are more memory efficient than list as they don't over allocate memory . Okay, so what this means is, when a list is created it takes up and reserves extra spaces of memory than needed for the original elements as new elements might be added to the list later and allocating memory on every addition would be quite inneficient but tuples, once created surelly won't change the numbers of elements in it later on, so it allocates exactly how much memory is needed. Almost all the list operations work for tuples except the ones which mutate it, for example, insert, append, remove etc. Declaring a tuple : Tuples can be initialise in a manner similar to list, But there's an important c
