It makes no sense to convert a list to a tuple given that tuples are specifically intended for collections of heterogeneous types whilst a list is a collection of homogeneous types. If the intent is simply to reduce memory consumption, then converting the list to an array would achieve the exact same result as converting to a tuple.

What are tuples in the python programing language?
In Python, a tuple is simply a list of immutable objects. The two main differences are that a list is initialised using square brackets, while a tuple is initialised with parenthesis and you cannot remove or modify elements of a tuple, but you can with a list.
How do we tuple initialize a class or structure?
Consider the following structure: struct X { int a; double b; // ... }; Here we could initialise with a std::tuple<int, double>. To achieve this we simply define a constructor that accepts the required tuple: #include<tuple> struct X { int a; double b; X::X (std::tuple<int, double>& t): a {std::get<0>(t)}, b {std::get<1>(t)} {} // ... }; Note that any constructor that has one argument is known as a conversion constructor, in this case converting from tuple to X. It is usually a good idea to declare such constructors explicit, particularly if you also provide the complementary conversion operator (from X to tuple). #include<tuple> struct X { int a; double b; explicit X::X (const std::tuple<int, double>& t): a {std::get<0>(t)}, b {std::get<1>(t)} {} operator std::tuple<int, double> (void) const {return std::make_tuple (a, b);} // ... };
How do you convert an integer to Boolean array list in java?
You cannot. An Integer is a numeric value whereas a boolean array list is a collection of a number of true or false values. So, you cannot convert either into the other
Convert single linked list to double linked list?
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
What is array variable?
An array is a variable containing multiple values. Any variable may be used as an array. There is no maximum limit to the size of an array, nor any requirement that member variables be indexed or assigned contiguously. Arrays are zero-based: the first element is indexed with the number 0.

Duplicate tuples not allowed in a relation?
In a relation we have number of tuple R ={t1,t2,t3.....tn}, nd they follow integrity constraints nd each tuple has a primary key pk.if any of the d two tuple have same attribute. for instance t1=t2 then its pk wud be same too.. but this violates the key constraint.. hence duplicacy not allowed in tuple... enjoy Rijo Rajan
