Element Values Assigned to List in Python

Element Values Assigned to List in Python. This program will print the list value which is initialized in program for data structure. This program is very similar to the previous program in data structure in python programming language.

The built-in list type “list” in Python is fantastic. Within square brackets [ ], list literals are written. Lists are similar to strings in that they are accessed using the len() function and square brackets [ ], with the first entry at index 0.

List and How it is Different From Tuples and Dictionary

Along with tuples, dictionaries, and sets, lists are one of Python’s four built-in data structures. They are used to hold an organised collection of objects that may or may not be of distinct sorts. The components included within a list are separated by commas and surrounded in square brackets. In Python, square brackets are the most common way of declaring a list. 

In Python, a list is an ordered sequence of zero or more elements. In Python, lists are mutable, meaning they can be modified. Any type of data, such as a string or a dictionary, can be stored in them. A list is made in Python by enclosing elements in square brackets [] and separating them with commas. A list can contain any number of items of various types. Another list can be an item in a list. A nested list is what it’s called.

How List is Useful in Python

When you need to work with a large number of linked values, lists are ideal. They let you to keep data that belongs together together, compress your code, and apply the same methods and actions to numerous variables at the same time.

Internally, Python lists are represented as arrays. The concept is similar to how vectors are implemented in C++ or how an Array List is implemented in Java. Inserting and deleting items near the beginning are the most expensive operations as everything has to be moved. If the pre allocated space is full, inserting at the end becomes costly as well.

How List is Implement in Python

Lists can be used to store a list of elements, as the name suggests. Lists, unlike traditional arrays, can expand and contract and are stored in memory dynamically. Sets, rather than a list, are implemented in efficient implementations using self-balancing binary search trees or hash tables.

num = [1,2,3,4,5,6]
print(num[0])
print(num[3])
print(num[5])

Output:

1
4
