We have a tuple of strings. We are required to create a list of elements which are the first character of these strings in the tuple.With indexWe design a for loop to take each element and extract the first character by applying the index condition as 0. Then the list ... Read More

We have a list of tuple. We are required to find out that tuple which was maximum value in it. But in case more than one tuple has same value we need the first tuple which has maximum value.With itemgetter and maxWith itemgetter(1) we get all the value from index ... Read More

We have a list whose elements are dictionaries. We need to flatten it to get a single dictionary where all these list elements are present as key-value pairs.With for and updateWe take an empty dictionary and add elements to it by reading the elements from the list. The addition of ... Read More

In this article we are required to find the first occurring non-zero number in a given list of numbers.With enumerate and nextWe sue enumerate to get the list of all the elements and then apply the next function to get the first non zero element.Example Live DemolistA = [0, 0, 13, ... Read More

Given a list of strings, lets find out the first non-empty element. The challenge is – there may be one, two or many number of empty strings in the beginning of the list and we have to dynamically find out the first non-empty string.With nextWe apply the next function to ... Read More

We are given a list whose elements are integers. We are required to find the relative order which means if they are sorted in ascending order then we need to find index of their positions.With sorted and indexWe first sort the entire list and then find out the index of ... Read More

In this article we will find out if all the tuples in a given list are of same length.With lenWe will use len function and compare its result to a given value which we are validating. If the values are equal then we consider them as same length else not.Example Live ... Read More

We have a list of tuples. In it we are required to find the top k frequent element. If k is 3 we are required to find the top three elements from the tuples inside the list.With defaultdictWe put the the elements into a dictionary container using defaultdict. Then find ... Read More

A list can have tuples as its elements. In this article we will learn how to identify those tuples which contain a specific search element which is a string.With in and conditionWe can design a follow with in condition. After in we can mention the condition or a combination of ... Read More

In this article we are required to find that number from the list which occurs odd number of times in the given list. We are also required to use the Lambda function and the reduce function.We design a function where the reduce function is used by applying the Lambda function ... Read More
