dynamic-sizedList: Lists are just like dynamic-sized arrays, declared in other languages (vector in C++ and ArrayList in Java). Lists need not be homogeneous always which makes it the most powerful tool in Python. The main characteristics of lists are –
- The list is a datatype available in Python which can be written as a list of comma-separated values (items) between square brackets.
- List are mutable .i.e it can be converted into another data type and can store any data element in it.
- List can store any type of element.
Example:
Python3
List = []
print("Blank List: ")
print(List)
List = [10, 20, 14]
print("\nList of numbers: ")
print(List)
List = ["Geeks", "For", "Geeks"]
print("\nList Items: ")
print(List[0])
print(List[2])
|
Output:
Blank List:
[]
List of numbers:
[10, 20, 14]
List Items:
Geeks
Geeks
Tuple: Tuple is a collection of Python objects much like a list. The sequence of values stored in a tuple can be of any type, and they are indexed by integers. Values of a tuple are syntactically separated by ‘commas’. Although it is not necessary, it is more common to define a tuple by closing the sequence of values in parentheses. The main characteristics of tuples are –
- Tuple is an immutable sequence in python.
- It cannot be changed or replaced since it is immutable.
- It is defined under parenthesis().
- Tuples can store any type of element.
Example:
Python3
Tuple1 = ()
print("Initial empty Tuple: ")
print (Tuple1)
list1 = [1, 2, 4, 5, 6]
print("\nTuple using List: ")
print(tuple(list1))
Tuple1 = tuple('Geeks')
print("\nTuple with the use of function: ")
print(Tuple1)
|
Output:
Initial empty Tuple:
()
Tuple using List:
(1, 2, 4, 5, 6)
Tuple with the use of function:
('G', 'e', 'e', 'k', 's')
Set: In Python, Set is an unordered collection of data type that is iterable, mutable, and has no duplicate elements. The major advantage of using a set, as opposed to a list, is that it has a highly optimized method for checking whether a specific element is contained in the set. The main characteristics of set are –
- Sets are an unordered collection of elements or unintended collection of items In python.
- Here the order in which the elements are added into the set is not fixed, it can change frequently.
- It is defined under curly braces{}
- Sets are mutable, however, only immutable objects can be stored in it.
Example:
Python3
set1 = set()
print("Initial blank Set: ")
print(set1)
String = 'GeeksForGeeks'
set1 = set(String)
print("\nSet with the use of an Object: " )
print(set1)
set1 = set(["Geeks", "For", "Geeks"])
print("\nSet with the use of List: ")
print(set1)
|
Output:
Initial blank Set:
set()
Set with the use of an Object:
{'G', 's', 'e', 'o', 'r', 'F', 'k'}
Set with the use of List:
{'Geeks', 'For'}
