It's unordered and requires the keys to be hashable. Python Data type: Unordered Collections An unordered collection is a set of one or more mutable or immutable data items, not necessarily of the same data type. >>> tup = (2,2,8,3) >>> tup (2, 2, 8, 3) Set is a collection which is unordered and unindexed. Tuples can store duplicate values. Found inside – Page 48Instead, Python uses named tuples, which provide some of the same functionality, but they're much more efficient because the instances don't need to contain any of the keys, only the values associated ... are considered to be unordered. In Python dictionary, it is an unordered collection of data that contains elements in the form of key-value pair whereas a tuple is an ordered collection of data that contains simple characters or integers and is represented by commas. This is done in order to allow Python to differentiate between a tuple and a pair of parentheses surrounding the object in some expression. Dictionary - mutable key/value pair. A Python tuple can also be created without using parentheses. List and Tuple objects are sequences.
