#Python object and data structure basics code#
When you repeat a block of code several times using a for loop, you are iterating the block of code. Cannot-be-changed doesn’t sound as grand as immutable! My aim in this book is the opposite, but we cannot escape using the terms you’ll find in documentation, error messages and other texts. Like in every other profession, programmers like to use complex-sounding words to make the subject look difficult and elusive. In this section, you’ll learn about sequences, iterables, mutable and immutable data types.

This is because some data types may have similar properties, and when you know how to deal with a category of data type, you’ll be better equipped to deal with a new data type you’ll encounter from the same category. Many, many more!Īs you learn about more data types, it is helpful to learn about the categories of data types. There are many more data types in Python.
You’ve used integers and floats, strings, Booleans, and lists. You’ve already come across several of the most important data types in Python. Can you guess the five most common words in Pride and Prejudice? You’ll find out the answer when you complete the project later on in this Chapter. In the second part, you’ll work on a new project in which you’ll work out all the words that Jane Austen used when writing Pride and Prejudice and how often she used each word. The first part of this Chapter will cover some of the theory related to data types. In this Chapter, you’ll read about how data types are handled in Python and about the different categories of data types. Languages such as Python provide many alternatives for you to consider. And if you’re using a programming language, you’ll want to perform some actions with the data and transform it in one way or another.ĭeciding how you want your program to store the data is an important decision you’ll need to make as a programmer. The data could be a simple name or number as in the Angry Goblin game, or you could have a very complex and highly structured data set. No computer program can exist without data. And then you need to do something with that information. You need information in any computer program. Granted, this is not the most detailed and technical definition you’ll find, but it summarises a program perfectly.
