Modern Python Cookbook

Statements and Syntax

Python syntax is designed to be simple. There are a few rules; we'll look at some of the interesting statements in the language as a way to understand those rules. Concrete examples can help clarify the language's syntax.

We'll cover some basics of creating script files first. Then we'll move on to looking at some of the more commonly-used statements. Python only has about 20 or so different kinds of imperative statements in the language. We've already looked at two kinds of statements in Chapter 1, Numbers, Strings, and Tuples, the assignment statement and the expression statement.

When we write something like this:

>>> print("hello world")
hello world

We're actually executing a statement that contains only the evaluation of a function, print(). This kind of statement—where we evaluate a function or a method of an object—is common.

The other kind of statement we've already seen is the assignment statement. Python has many variations on this theme. Most of the time, we're assigning a single value to a single variable. Sometimes, however, we might be assigning two variables at the same time, like this:

quotient, remainder = divmod(355, 113)

These recipes will look at some of the more common of the complex statements, including if, while, for, try, and with. We'll touch on a few of the simpler statements as we go, like break and raise.

In this chapter, we'll look at the following recipes:

  • Writing Python script and module files - syntax basics
  • Writing long lines of code
  • Including descriptions and documentation
  • Better RST markup in docstrings
  • Designing complex if...elif chains
  • Saving intermediate results with the := "walrus"
  • Avoiding a potential problem with break statements
  • Leveraging exception matching rules
  • Avoiding a potential problem with an except: clause
  • Concealing an exception root cause
  • Managing a context using the with statement

We'll start by looking at the big picture – scripts and modules – and then we'll move down into details of individual statements. New with Python 3.8 is the assignment operator, sometimes called the "walrus" operator. We'll move into exception handling and context management as more advanced recipes in this section.

I read all Steven's books, and I like them a lot. This one was no exception—great examples for many different use cases. I really enjoyed and read several times chapter about testing using pytest. If you want to learn about python testing without reading books with many pages, this chapter will give you most of what you need.Another thing that I like about this book that it's truly embracing new python features, such as data typing. In the whole book, every single function uses typing, and in many cases, Steve explains why he decided to use TypedDict instead of NamedTuple or dataclass.I read this book from beginning to end, and I will continue to use it as a reference.I also recommend reading and look at the code at GitHub since it has much more code than in the book, where you will learn much more from the code.

I came across this book and got immediately hooked into it. I loved the clean and concise explanation which helped me solve tasks which was very difficult especially the concepts of classes. I would highly recommend this book and make sure you keep in handy so that you can have a quick overview without watching internet

As I do not use Python on a regular base, I need a reminder or refresher from time to time. This book lends itself very well for that kind of "I know python but I am rusty" type of individual. I also see this fit in as a resource for people who program in Python every day, as reference material.The book is well written and covers any imaginable topic related to the python scripting language. I highly recommend this book for everyone that likes to program in Python (from time to time).

I first read Lott’s "Mastering Object-Oriented Python", which is an excellent book. He is an excellent writer who can easily dive into the technical details of any topic in Python.O’Reilly was the first company to put out a Python Cookbook. That book is good too and it’s nearly as large as Lott’s latest work. Cookbooks aren’t meant to be read cover-to-cover. But they are great for learning new nuggets of information. Lott’s book is arranged in groups of recipes. Interestingly, Packt was able to get the author of the first Python Cookbook, Alex Martelli, to be one of the technical reviewers for this one.There are 15 chapters with a varying number of recipes in each. You will be surprised how detailed the recipes get. For example, there is a recipe called “Working with large and small integers” which sounds trivial at first blush. But after reading through it, you will learn a lot about how Python represents integers differently than other programming languages.It also explains how sys.maxsize() comes into play which was actually much more interesting than I expected. I appreciated that the recipes have a “See Also” section that tells you where to go next to learn something related within the book or at a URL.I like that there are recipes that explain how to use the walrus operator, forcing keyword-only arguments and position only arguments too. There’s a lot of good coverage of new features in the latest versions of Python here.You will also learn about classes, objects and functional programming in this book.Amazingly, the author covers web services, configuration, combining applications, statistical programming and linear regression too!You should check this book out. It’s really interesting and will be a great reference book.
