Hence any operation that tries to modify it (like append) is not allowed. Then use another built-in function tuple() to convert this list object back to tuple. This book doesn’t provide extensive coverage of tuples, but they work so well in returning complex data that you definitely need to know something about this use of tuples. Expressive code in C++. Creating a Tuple. Home. Lists and tuples are arguably Python’s most versatile, useful data types.You will find them in virtually every nontrivial Python program. Using ‘+’ operator: As we know tuples are immutable data structures and we can not directly add items to it, so by creating a variable or directly adding value using ‘+’ operator will do the work of adding the single item in tuple, following block of code will make a clear understanding.
