Python, a versatile and widely used programming language, provides a rich set of data structures to accommodate various programming needs. One of the fundamental data structures in Python is the list, a dynamic array that allows the storage of heterogeneous elements. While lists are powerful, there are situations where other data structures might be more suitable for specific tasks. This article explores how Python lists can be transformed into other data structures to enhance efficiency and optimize code....

List and tuples both are data structures in Python, with some differences. Lists are mutable data structures whereas tuples are immutable (can not be changed after creating it)....

Python, a versatile and powerful programming language, offers multiple ways to manipulate and process data. When working with a list of dictionaries, you may often need to filter the data based on specific key-value pairs. In this article, we will explore three different methods to achieve this task: using list comprehension, the filter function, and a traditional for loop....

Given a List of Integers. The task is to convert them to a List of Strings....

Sometimes we need to perform the operation of removing all the items from the lists that are present in another list, i.e we are given some of the invalid numbers in one list which need to be get ridden from the original list. Let’s discuss various ways How to remove the elements of a list from another list in Python....

Some of the list methods are mentioned in set 1 below...

Python’s built-in module in random module is used to work with random data. The random module provides various methods to select elements randomly from a list, tuple, set, string or a dictionary without any repetition. Below are some approaches which depict a random selection of elements from a list without repetition by: Method 1: Using random.sample() Using the sample() method in the random module. The sample() is an inbuilt method of the random module which takes the sequence and number of selections as arguments and returns a particular length list of items chosen from the sequence i.e. list, tuple, string or set. It is used for random selection from a list of items without any replacement. Example 1:...

Lists and Dictionaries in Python are inbuilt data structures that are used to store data. Lists are linear in nature whereas the dictionaries stored the data in key-value pair. In this article, we will see the difference between the two....

In this article, we will discuss how to convert a list of dictionaries to a dictionary of lists....

The problem of finding maximum and minimum values in a list is quite common. But sometimes this problem can be extended in two lists and hence becomes a modified problem. This article discusses shorthands by which this task can be performed easily. Let’s discuss certain ways in which this problem can be solved....

One of the problems that is basically a subproblem for many complex problems, finding numbers greater than a certain number in a list in python, is commonly encountered and this particular article discusses possible solutions to this particular problem....

Given a 2D list, write a Python program to find the most common element in each column of the 2D list. Examples:...
