Python Tutorial for Beginners 2020 - Dictionary
Hey guys, this is the 13th video for my Python's tutorial course for beginners. We will be covering all the basics about Python including installing and setting up the development environment, variables, data structures, iterations, conditionals, operators, error handlings, functions, classes and many more. The aim for this tutorial is to provide with a solid foundation layer for Python and programming in general so that we can proceed to more advanced level Python tutorials and also look into different application areas of using Python such as web development and data science.
In this video, we are going to talk about dictionary data type in Python. Dictionary is one of the most frequently used and important data type in Python because it provides the programmer with the ability to control the data in a more flexible manner, and the dictionary’s characteristics of unordered, indexed, and being mutable makes the dictionary even more special. So the video will start with talking about the key and value concept or the dictionary and we will move on to inserting, updating, and deleting elements in the dictionary using Key. And also we will talk about few of the dictionary class methods in this video with some examples.
