Given two lists containing integers, the task is to find the sum of the frequency of elements of the first list in the second list....

We generally come through the task of getting certain index values and assigning variables out of them. The general approach we follow is to extract each list element by its index and then assign it to variables. This approach requires more line of code. Let’s discuss certain ways to do this task in compact manner to improve readability....

Given a String list, the task is to write a Python program to convert uppercase strings if the length is greater than K....

Sometimes, while working with Python lists, we can have a problem in which we need to convert the string list to Character Matrix where each row is String list column. This can have possible application in data domains. Lets discuss certain ways in which this task can be performed....

Sometimes in the world of competitive programming, we need to initialise the matrix, but we don’t wish to do it in a longer way using a loop. We need a shorthand for this. This type of problem is quite common in dynamic programming domain. Let’s discuss certain ways in which this can be done....

As we know Array is a collection of items stored at contiguous memory locations. In Python, a List (Dynamic Array) can be treated as an Array. In this article, we will learn how to initialize an empty array of some given size. Let’s see different Pythonic ways to create an empty list in Python with a certain size....

Sometimes, while working with Python list, we can have a problem in which we need to perform shuffle operation in list. This task is easy and there are straightforward functionalities available in Python to perform this. But sometimes, we need to shuffle two lists so that their shuffle orders are consistent. Let’s discuss a way in which this task can be performed.Method : Using zip() + shuffle() + * operator In this method, this task is performed in three steps. Firstly, the lists are zipped together using zip(). Next step is to perform shuffle using inbuilt shuffle() and last step is to unzip the lists to separate lists using * operator....

Sometimes, in making programs for gaming or gambling, we come across the task of creating the list all with random numbers and perform its summation. This task has to performed in general using loop and appending the random numbers one by one and then performing sum. But there is always requirement to perform this in most concise manner. Lets discuss certain ways in which this can be done....

Given a list and two elements, x and y find the nearest occurrence index of element x from element y....

Sometimes, while working with Python lists, we can have a problem in which we need to perform addition of lists in diagonal manner that i.e. adding ith element of 1 list to i + 1 element of other list. This kind of problem can have application in day-day programming. Lets discuss certain ways in which this task can be performed....

Given a list of strings, perform concatenation of Strings whose length is greater than K....

Given a list of dictionaries, extract all the values summation....
