Points to remember:
·
Python programming language has four collections of data types such
as List, Tuple, Set and Dictionary.
·
A list is known as a “sequence data type”. Each value of a list is
called as element.
·
The elements of list should be specified within square brackets.
·
Each element has a unique value called index number begins with
zero.
·
Python allows positive and negative values as index.
·
Loops are used access all elements from a list.
·
The “for” loop is a suitable loop to access all the elements one by
one.
·
The append ( ), extend ( ) and insert ( ) functions are used to
include more elements in a List.
·
The del, remove ( ) and pop ( ) are used to delete elements from a
list.
·
The range ( ) function is used to generate a series of values.
·
Tuples consists of a number of values separated by comma and
enclosed within parentheses.
·
Iterating tuples is faster than list.
·
The tuple ( ) function is also used to create Tuples from a list.
·
Creating a Tuple with one element is called “Singleton” tuple.
·
A Set is a mutable and an unordered collection of elements without
duplicates.
·
A set is created by placing all the elements separated by comma
within a pair of curly brackets.
·
A dictionary is a mixed collection of elements.
