What's included
Description
In this course, you will study dictionaries (collections of key-value pairs) and sets (a related type of collections). You will learn their internal structure and the syntax for creating and modifying them. As a result, you will learn how to create and copy data from dictionaries and manipulate dictionaries with keys, values, and item iterators. You will learn how to perform various operations on sets: union, difference, intersection, and subset checking. In this course, you will gain the skills necessary to work with hash structures in Python, which you can use to describe entities in any domain. To make learning easier, you should complete the Python Fundamentals and Python Lists courses before taking this course.
You will learn
- Understand the structure of dictionaries
- Use dictionaries, create and change them
- Create and manipulate sets
- Process dictionaries with keys, values, and items iterators
