A Dictionary is an unordered collection of data structure which stores the elements as key and value. It is mutable and in other programming languages Dictionaries are also known as associative arrays, hash maps, or hash tables. The key is the unique one and the values are of a single element or a list of elements with duplicates. A Dictionary can be created by using the curly braces {} or by using the built in function dict(). Let’s see an example of creating the dictionary in python. Example student = { 'name': 'Tutorialspoint', 'age': ... Read More

Progress bars in Python are visual indicators that provide feedback on the progress of a task or operation. They are useful for long-running processes or iterations where it's helpful to show how much work has been completed and how much is remaining. A progress bar typically consists of a visual representation, such as a horizontal bar or a textual representation, which dynamically updates to reflect the progress of the task. It also includes additional information like the percentage of completion, estimated time remaining, and any relevant messages or labels. The following are the purposes served by the progress bars in ... Read More

Programming paradigm is a specific approach or style of programming that provides a framework for designing and implementing computer programs. It encompasses a set of principles, concepts, and techniques that guide the development process and the structure of the code. Different paradigms have different ways of solving problems, organizing code, and expressing computations. The below are the various programming paradigms available in python which makes the developer work easy and more efficient. Procedural Programming Procedural programming focuses on dividing a program into a set of procedures or functions. In Python, we can define functions to perform specific tasks and structure ...

The doomsday is also known as the doomsday of the week which is a specific day of the week that falls on the same date every year. The concept of the doomsday is based on the doomsday algorithm, which allows us to determine the day of the week for any given date. The doomsday algorithm was developed by mathematician John Horton Conway and is based on the idea that certain dates within each year fall on the same day of the week called the doomsday. The doomsday occurs on the following dates − January 3rd February 7th or 14th ... Read More
