Download Real Python: An Introduction to Python Through Practical by Fletcher Heisler PDF

By Fletcher Heisler

An book to coach programming via hands-on, fascinating examples which are invaluable and fun!

Python is a brilliant programming language. It's unfastened, robust, more uncomplicated to learn than so much languages, and has extensions to be had to do virtually something you may think automatically.

But how do you certainly use it? There are hundreds assets available in the market for studying Python, yet none of them are very useful or attention-grabbing - as a substitute, they cross over each one inspiration one after the other, by no means tying whatever jointly, yet spending lots of time misplaced in technical language, discussing the twenty alternative ways to complete every one simple task...

I are looking to write an booklet that eventually offers a concise creation to every thing chances are you'll really are looking to do with Python.

We'll begin with a brief yet thorough assessment of all of the fundamentals, so that you don't even want any past event with programming. however the majority of the booklet could be spent increase instance code to unravel fascinating real-world problems.

Python is amazing for automating repetitive initiatives that will in a different way take you hours - for example, fast accumulating info from the internet, or renaming 1000s of records. many of the subject matters that I'm making plans to cover:

Collecting facts from webpages (web scraping)
Interacting with PDF documents - interpreting information, growing PDFs, enhancing pages, including passwords...
Interacting with Excel documents (less performance in OS X)
Calling different open air courses from inside of Python
Files - read/write/modify, unzip, rename, movement, etc.
Basic online game development
Interacting with SQL databases (internal and ODBC connections)
GUI (Graphical consumer Interface) layout - growing basic point-and-click courses that anybody can use
Any different subject matters that you simply, my backers, are such a lot in!
Update: through renowned call for, I'll be including internet software 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 publication is sharply considering classical algorithms, however it additionally provides a fantastic realizing of basic algorithmic problem-solving options.

The ebook offers with the most very important and demanding parts of programming and computing device technological know-how, yet in a hugely pedagogic and readable manner.

The booklet covers either algorithmic conception and programming perform, demonstrating how thought is mirrored in actual Python programs.

Well-known algorithms and information constructions which are outfitted into the Python language are defined, and the consumer is proven the way to enforce and review others himself.

Testing Python: Applying Unit Testing, TDD, BDD and Acceptance Testing

Primary trying out methodologies utilized to the preferred Python language

Testing Python; utilising Unit checking out, TDD, BDD and reputation checking out is the main finished e-book to be had on trying out for one of many most sensible software program programming languages on the earth. Python is a traditional selection for brand new and skilled builders, and this hands-on source is a miles wanted advisor to enterprise-level checking out improvement methodologies. The ebook will exhibit you why Unit checking out and TDD can result in purifier, extra versatile programs.

Unit checking out and Test-Driven improvement (TDD) are more and more must-have abilities for software program builders, it doesn't matter what language they paintings in. In company settings, it's severe for builders to make sure they continually have operating code, and that's what makes checking out methodologies so beautiful. This e-book will train you the main common trying out recommendations and should introduce to you to nonetheless others, protecting functionality checking out, non-stop checking out, and more.

Learn Unit checking out and TDD—important improvement methodologies that lie on the middle of Agile development
Enhance your skill to paintings with Python to advance robust, versatile purposes with fresh code
Draw at the services of writer David Sale, a number one united kingdom developer and tech commentator
Get prior to the gang through studying the underappreciated global of Python testing
Knowledge of software program checking out in Python may set you except Python builders utilizing superseded methodologies. Python is a typical healthy for TDD and checking out Python is a must-read textual content for a person who desires to boost services in Python programming.

Sample text

Notice how you can hit tab and backspace to change indentation, and IDLE automatically inserts four space characters? That's because you can't mix tabs and spaces as indentation. or at least until you manage to forcibly quit out of IDLE using your panic key combination of choice. com Real Python would get confused – even though the spacing looks the same to you! ) The second type of loop, a for loop, is slightly different in Python. We typically use for loops in Python in order to loop over every individual item in a set of similar things – these things could be numbers, variables, lines from an input file, etc.

7 Likewise, an “else” placed after a while loop will always be run unless the while loop has been exited using a break statement. For instance, try out the following script: tries = 0 while tries < 3: password = raw_input("Password: ") if password == "I<3Bieber": break else: tries = tries + 1 else: print "Suspicious activity. " Here, we've given the user three chances to enter the correct password. If the password matches, we break out of the loop. Otherwise (the first else), we add one to the “tries” counter.

The second “else” block belongs to the loop (hence why it's less indented than the first “else”), and will only be run if we don't break out of the loop. , the user tried three incorrect passwords), then it's time to alert the authorities. 5) Recover from errors Y ou've probably already written lots of scripts that generated errors in Python. Runtime errors (so-called because they happen once a program is already running) are called exceptions. Congratulations – you've made the code do something exceptional!
