Описание: In this video, we dive deep into Dictionary Methods in Python, one of the most important topics for mastering Python data structures. Python dictionaries are powerful, flexible, and widely used for storing data in key-value pairs. Understanding Python dictionary methods is essential for beginners, intermediate learners, and anyone preparing for Python interviews, data science, machine learning, or web development.

This tutorial explains all major dictionary methods in Python with clear examples and practical use cases. You will learn how to create dictionaries and efficiently manipulate data using built-in dict methods. We start with commonly used methods like dict.keys(), dict.values(), and dict.items(), which help you access dictionary keys, values, and key-value pairs. These methods are especially useful when looping through dictionaries using for loops.

Next, we cover safe data access using the dict.get() method, which prevents errors when a key is missing. You will also learn how to modify dictionaries using dict.update() to add or update multiple key-value pairs at once. Deleting elements is explained using dict.pop(), dict.popitem(), and del, along with real-world examples.

The video also explains utility methods such as dict.clear() to remove all items, dict.copy() for creating shallow copies, and dict.fromkeys() for generating new dictionaries from a sequence of keys. We also explore dict.setdefault(), a powerful method that helps initialize keys with default values.

In addition, this tutorial discusses essential dictionary operations like checking key existence using the in operator, finding the length of a dictionary using len(), and comparing dictionaries. You’ll learn best practices for working with dictionaries efficiently and avoiding common mistakes.

By the end of this video, you will have a strong understanding of Python dictionary methods, how dictionaries work internally, and how to use them in real-world Python programs. This lesson is perfect for anyone learning Python programming, core Python, object-oriented programming in Python, or preparing for coding interviews.
