Learning Python: Powerful Object-Oriented Programming (4th Edition)
Google and YouTube use Python simply because it's hugely adaptable, effortless to take care of, and allows fast improvement. that will write fine quality, effective code that's simply built-in with different languages and instruments, this hands-on publication can help you be effective with Python fast -- no matter if you're new to programming or simply new to Python.
Real Python: An Introduction to Python Through Practical Examples
An book to educate programming via hands-on, fascinating examples which are important and fun!
Python is a smart programming language. It's unfastened, robust, more straightforward to learn than such a lot languages, and has extensions to be had to do nearly whatever you may think automatically.
But how do you definitely use it? There are a whole bunch assets available in the market for studying Python, yet none of them are very functional or attention-grabbing - in its place, they pass over every one suggestion one after the other, by no means tying something jointly, yet spending lots of time misplaced in technical language, discussing the twenty alternative ways to complete every one simple activity. ..
I are looking to write an booklet that at last offers a concise advent to every little thing you may truly are looking to do with Python.
We'll begin with a short yet thorough review of all of the fundamentals, so that you don't even want any past event with programming. however the majority of the booklet can be spent build up instance code to unravel attention-grabbing real-world problems.
Python is amazing for automating repetitive projects that may differently take you hours - for example, fast amassing information from the internet, or renaming hundreds of thousands of records. a few of the issues that I'm making plans to cover:
Collecting facts from webpages (web scraping)
Interacting with PDF documents - studying facts, developing PDFs, enhancing pages, including passwords. ..
Interacting with Excel documents (less performance in OS X)
Calling different outdoor courses from inside of Python
Files - read/write/modify, unzip, rename, circulate, etc.
Basic online game development
Interacting with SQL databases (internal and ODBC connections)
GUI (Graphical person Interface) layout - developing easy point-and-click courses that any one can use
Any different subject matters that you just, my backers, are such a lot in!
Update: by means of well known call for, I'll be including net program development

Python Algorithms: Mastering Basic Algorithms in the Python Language
Python Algorithms explains the Python method of set of rules research and layout.
Written through Magnus Lie Hetland, writer of starting Python, this ebook is sharply taken with classical algorithms, however it additionally offers a pretty good figuring out of basic algorithmic problem-solving thoughts.
The ebook bargains with one of the most very important and not easy parts of programming and desktop technological know-how, yet in a hugely pedagogic and readable manner.
The e-book covers either algorithmic conception and programming perform, demonstrating how concept is mirrored in genuine Python programs.
Well-known algorithms and information buildings which are equipped into the Python language are defined, and the person is proven the right way to enforce and overview others himself.
Testing Python: Applying Unit Testing, TDD, BDD and Acceptance Testing
Primary trying out methodologies utilized to the preferred Python language
Testing Python; utilizing Unit trying out, TDD, BDD and recognition checking out is the main finished e-book on hand on trying out for one of many most sensible software program programming languages on the earth. Python is a common selection for brand new and skilled builders, and this hands-on source is a miles wanted consultant to enterprise-level trying out improvement methodologies. The booklet will exhibit you why Unit checking out and TDD may end up in purifier, extra versatile programs.
Unit trying out and Test-Driven improvement (TDD) are more and more must-have talents for software program builders, it doesn't matter what language they paintings in. In company settings, it's serious for builders to make sure they regularly have operating code, and that's what makes trying out methodologies so appealing. This e-book will educate you the main ordinary trying out thoughts and should introduce to you to nonetheless others, masking functionality trying out, non-stop trying out, and more.
Learn Unit checking out and TDD—important improvement methodologies that lie on the center of Agile development

The dashes in the previous screenshot indicate a missing value. This doesn't necessarily correspond to an error condition. For example, if the page is not password-protected then there will be no remote user. The dash is a common condition we'll need to handle. [ 30 ] Chapter 2 For more information on web server log formats and available data points, please see your web server documentation. html Time for action – generating transfer statistics Now, let's start our processor. Initially, we'll build enough functionality to scan our logfile as read via standard input and report files served over a given size.
You saw how to create a new instance via the virtualenv command and you also learned how to subsequently activate it using the bin/activate script. Finally, we showed you how to deactivate your environment and return to your system's default state. Have a go hero – install your own environment Now that you know how to set up your own isolated Python environment, you're encouraged to create a second one and install a collection of third-party utilities in order to get the hang of the installation process.
If you entered everything correctly, your output should be as follows. py -s What just happened? We added support for a new log input format simply by replacing the parse method of our log processor. We did this by inheriting from LogProcessor and creating a new class, overriding parse. There are no additional changes required to support an entirely new format. As long as your new LogProcessor class implements the required methods and returns the proper values, it's a piece of cake. Your LogProcessor subclass could have done something much more elaborate, such as process each line via regular expressions or handle missing elements gracefully.
