Python Keywords An Introduction

In this article, you will learn about Python keywords. These are the pre-defined reserve words in Python. Each keyword has its own specific identity and assigned task.  

In Python, these keywords cannot be used as variable names, function names, and other identifiers. If we use them as variables the Python interpreter treats them as keywords. There are almost 35 keywords in Python. They may vary depending on which Python version you are using.
