There are the composite data types which can be used as an array of data in which elements exist in some specific intrinsic ordering, which helps in retrieval of the data. A mutable data type means that a python object of this type can be modified. A dictionary is a key-value store. The biggest difference between these data structures is their usage: Lists - for ordered sequence of objects Tuple - can be considered as immutable list Python Set - unique list Python Dictionary / dict - pair of key and values The The tuple is faster than the list because of static in nature. $\begingroup$ This is customary usage, not part of a formal definition.
