Given 2 lists, print the element in zig-zag manner, i.e print similar indices of lists and then proceed to next....

Given an array, cyclically rotate the array clockwise by one. In this article, we will see how to cyclically rotate an array by one in Python....

Sometimes, we require to reduce the length of the python list but other times we might also require to increase its size, and that too by repeating every element N times. This type of utility can come in day-day programming. Let’s discuss certain ways in which this can be achieved....

Given a List of elements, test if all elements are even in a range....

Sometimes, we come across an issue in which we require to delete the first K characters from each string, that we might have added by mistake and we need to extend this to the whole list. This type of utility is common in web development. Having shorthands to perform this particular job is always a plus. Let’s discuss certain ways in which this can be achieved....

Sometimes, while working with Python lists, we can have a problem in which we require to extract every Kth element of list and slice out a new list from that. This type of problems are quite common as a variation of list slicing. Let’s discuss a way in which this can be done. Method : Using list slicing This task can be performed using list slicing functionality. The trick here is to use the skip functionality of list to get every Kth element of list. K, as defined can be used as skip element....

Given a list. The task is to convert it to a dictionary with the values as the list element and keys as the concatenation of the given string K and value....

Given a list of dictionary, convert to dictionary with same key mapped with all values in as value list....

Sometimes, while working with Python lists, we can have a problem in which we need to remove all the negative elements from list. This kind of problem can have application in many domains such as school programming and web development. Let’s discuss certain ways in which this task can be performed....

Sometimes, while working with Python lists, we can have a problem or part of it, in which we desire to convert a list after deletion of some random element. This can have it’s application in gaming domain or personal projects. Let’s discuss certain way in which this task can be done....

The task of removing duplicates many times in the recent past, but sometimes when we deal with the complex data structure, in those cases we need different techniques to handle this type of problem. Let’s discuss certain ways in which this task can be achieved....

Sometimes, while working with lists, we can have a problem in which we need to group all the sublists, separated by elements present in different list. This type of custom grouping is uncommon utility but having solution to these can always be handy. Lets discuss certain way in which this task can be performed. Method #1 : Using loop + generator(yield) This is brute force way in which this task can be performed. In this, we iterate the list and make groups dynamically using yield. We keep track of elements occurred and restart list when we find element in second list....
