Unit II STRING, LIST, TUPLE, DICTIONARY
Sequence Data types. Operations on sequence data types: Indexing and slicing,
concatenation, and replication, in and not in operators to access elements. List:
Creation, mutable property, In build methods of List: index (), append (), insert (),
sort (), reverse (). Tuple: immutable property, converting types using tuple (), list
(). Dictionary Data type: Creation, keys (), values () and items () methods.
