Many coders struggle with understanding the zip function. Let’s fix this! The zip() function takes an arbitrary number of iterables and aggregates them to a single iterable, a zip object. It combines the i-th values of each iterable argument into a tuple. Hence, if you pass two iterables, each tuple will contain two values. If … Read more

The min() function returns the minimum of the provided arguments. As arguments, you can either pass a number of comma-separated values, or a single iterable. An optional key function argument allows you to customize the calculation of the minimum by explicitly defining the weight of each value in the iterable that is used as a … Read more
Summary: One of the following methods can be used to check if a list is empty :- Method 1: Using isinstance() With any() Method 2: Using isinstance() And len() Methods Within For Loop Problem: Given a list; how to check if it is nested or not? Considering that you have a list such that it is nested at … Read more
The max() function returns the maximum of the provided arguments. You can pass either an arbitrary number of values, comma-separated, or an iterable as arguments. An optional key function argument allows you to customize the calculation of the maximum by explicitly defining the weight of each value in the iterable that is used as a … Read more
Python’s built-in tuple() function creates and returns a new tuple object. When used without an argument, it returns an empty tuple. When used with the optional iterable argument, it initializes the new tuple with the elements in the iterable. Read more about tuples in our full tutorial about Python Tuples. Usage Learn by example! Here … Read more
Python’s built-in list() function creates and returns a new list object. When used without an argument, it returns an empty list. When used with the optional iterable argument, it initializes the new list with the elements in the iterable. Read more about lists in our full tutorial about Python Lists. Usage Learn by example!

Recap: Python’s map() function takes a function and an iterable—such as a list—as arguments. It then applies the function to each element in the iterable. It returns a map object. ? But what if you don’t need a map object but a list? Old: In Python 2.x this was easy: the map() function simply returned … Read more
The map() function transforms one or more iterables into a new one by applying a “transformator function” to the i-th elements of each iterable. The arguments are the transformator function object and one or more iterables. If you pass n iterables as arguments, the transformator function must be an n-ary function taking n input arguments. … Read more
There are three problem variants of finding the maximum value in a Python dictionary: In the following, you’ll learn how to solve those in the most Pythonic way: Find Maximum Value & Return Only Value The output is: Find Maximum Value & Return (Key, Value) Pair The output is: Find Maximum Value & Return Only … Read more
For a coder, understanding the Quicksort algorithm is like knowing the secret of 42—either you get it, or you don’t belong to the club. If you don’t know either, let’s work on the first one! The Quicksort Algorithm — A Python Implementation The algorithm is a variant of the popular Quicksort algorithm. The function qsort … Read more
If you’re like me, you want to come to the heart of an issue fast. Here’s the 1-paragraph summary of the enumerate() function—that’s all you need to know to get started using it: Python’s built-in enumerate(iterable) function allows you to loop over all elements in an iterable and their associated counters. Formally, it takes an … Read more
