Understanding List Comprehension List comprehension is a concise way to create lists in Python. They offer a shorter syntax to achieve the same result as using a traditional for loop and a conditional statement. List comprehensions make your code more readable and efficient by condensing multiple lines of code into a single line. The basic … Read more
Python’s built-in sorted() function enables programmers to sort a list efficiently and easily. On the other hand, the list.sort() method provides an in-place sorting mechanism. Additionally, Python allows for custom sorting using the key parameter in these functions, enabling more advanced sorting scenarios. In this article, I’ll show you how to find an element in … Read more
Joining two lists in Python is a common operation when working with data structures, as it allows you to merge different sets of information highly efficiently. Python offers other approaches to combine lists, such as list comprehension and extending lists. The easiest approach is the ‘+‘ operator as it stands out for its simplicity and … Read more
If you’re working with Python, most of the data structures you’ll think about are container types. 🚂🚃🚃🚃 These containers are special data structures that hold and manage collections of elements. Python’s most commonly used built-in container types include tuples, lists, dictionaries, sets, and frozensets 📦. These containers make it easy for you to store, manage … Read more
Problem Formulation and Solution Overview This article will show you how to add elements to a Python set. ℹ️ Info: A Python set is a collection of unique item(s) saved in no particular order (unordered). A set cannot be changed. However, elements can be added and removed. Sets can also perform calculations like union, intersection, … Read more
Problem Statement: Consider that you have been given a list in Python. How will you count the number of unique values in the list? Example: Let’s visualize the problem with the help of an example: Given: li = [‘a’, ‘a’, ‘b’, ‘c’, ‘b’, ‘d’, ‘d’, ‘a’]Output: The unique values in the given list are ‘a’, ‘b’, ‘c’, ‘d’. … Read more
The most Pythonic way to print a dictionary except for one or multiple keys is to filter it using dictionary comprehension and pass the filtered dictionary into the print() function. There are multiple ways to accomplish this and I’ll show you the best ones in this tutorial. Let’s get started! 🚀 👉 Recommended Tutorial: How … Read more
Basic Solution To create a set of n elements, pass a list or another iterable of n initial elements into the set() function. For example, set(range(n)) creates the set of n consecutive integers {1, 2, …, n-1}. You can then add and remove the elements using the normal set methods such as add() or pop(). … Read more
Use Python’s built-in min() function with the key argument to find the shortest string in a set. Call min(my_set, key=len) to return the shortest string in the set using the built-in len() function to determine the weight of each string—the shortest string has minimum length. 👉 Recommended Tutorial: How to Find the Shortest String in … Read more
💬 Problem Formulation: Given a Python set. How to convert it to a tuple? And how to convert the tuple back to a set? There are three main ways: Method 1: To convert a Python set to a tuple, use the tuple(my_set) function. Method 2: To convert a Python tuple to a set, use the … Read more
There are three main ways to check if a set is empty: Implicit: Pass the set into a Boolean context without modification. Python will automatically convert it to a Boolean using bool(). Explicit: Pass the set into the bool() Function. Comparison: Compare the set with the empty set like so: my_set == set() Let’s dive … Read more
Use Python’s built-in max() function with the key argument to find the longest string in a set. Call max(my_set, key=len) to return the longest string in the set using the built-in len() function to determine the weight of each string—the longest string has maximum length. 👉 Recommended Tutorial: How to Find the Longest String in … Read more
