In this chapter, we have looked at two ways of running Python programs. We can run commands through the Python interactive shell or by running saved scripts. While you'll mostly find yourself running programs from saved scripts, you will find the freedom and quick gratification of using the interactive shell to run a quick check very convenient. These two methods will come in handy on your Python journey.

We have also covered the Python syntax in detail in this chapter. We started with variable assignment in Python. We looked at the different types of values Python variables can be assigned to, the syntax for assigning them, as well as the importance of reserved keywords in Python.

We then looked at the built-in input function and how it enables us to take input from a user keyboard. We looked at the different ways of writing comments in Python code, and then we finished the chapter by looking at the importance of indentation in writing readable, maintainable Python code.

In the next chapter, we will look at data types such as integers, strings, Booleans, and more.
