This is called tuple packing. index() Searches the tuple for a specified value and returns the position of where it was found. As you can see in the code below, you cannot update or change the values of tuple items (this is different from Python Lists which are mutable). Some pronounce it as though it were spelled “too-ple” (rhyming with “Mott the Hoople”), and others as though it were spelled “tup-ple” (rhyming with “supple”). I don't have a problem, just a general query about usage of the __methodname__ methods in the Tuple class and/or in general.. Tuples are defined by enclosing elements in parentheses (), separated by a comma. In someways a tuple is similar to a list in terms of indexing, nested objects and repetition but a tuple is immutable unlike lists which are mutable. Tuple data type is appropriate for accessing the elements: 4: Lists consume more memory: Tuple consume less memory as compared to the list: 5: Lists have several built-in methods : Tuple does no have must built-in methods. data, the other 3 are List, A tuple is an ordered collection of values.
