The dictionary is a collection of data items in the key-value pair and represented by the braces { }. The list is also a data type used to store the date and represented by the braces [ ]. The built-in Python method items() are used to retrieve all the keys and corresponding values. We can print the dictionary’s keys and values by combining the items() method with a for loop....
In this article, we will discuss how to randomly select n elements from the list in Python. Before moving on to the approaches let’s discuss Random Module which we are going to use in our approaches....
Given a List. The task is to find the sum and average of the list. The average of the list is defined as the sum of the elements divided by the number of elements....

Python List Methods are the built-in methods in lists used to perform operations on Python lists/arrays....
In Python, list slicing is a common practice and it is the most used technique for programmers to solve efficient problems. Consider a Python list, in order to access a range of elements in a list, you need to slice a list. One way to do this is to use the simple slicing operator i.e. colon(:). With this operator, one can specify where to start the slicing, where to end, and specify the step. List slicing returns a new list from the existing list....
Let’s see how to concatenate two lists using different methods in Python. This operation is useful when we have a number of lists of elements that need to be processed in a similar manner....
Appending elements to a list is a common operation in Python, and it’s essential to understand how to add elements to an empty list. In this article, we’ll explore different methods to append items to an empty list and discuss their use cases....
