  • Hello! And welcome to the online course for the Austomate the Boring Stuff with

  • Python book. I'm Al Sweigart. I'm a software developer and textbook author.

  • Automate the Boring Stuff with Python is my fourth programming book and now

  • I've made an online course that follows the book's content.

  • "Learn to code" has become a huge mantra. You have sites like Codecademy and Khan

  • Academy and a massive online open courses to teach people the program. You hear

  • things like, "coding is the new literacy" or how everyone in the 21st century will

  • have to learn to code.

  • And if you want to become a software developer this course can be your first

  • few steps on that path.

  • But what if you don't want to change careers to software engineering. You're

  • still getting these learn to code recommendations from everyone, mostly

  • from people with a book to sell.

  • (By the way Automate the Boring Stuff with Python is released under a Creative

  • Commons license, so you can buy a print or ebook or you can read it online for

  • free at automatetheboringstuff.com.

  • Is there a reason the average office worker student or administrator should

  • learn to code? Yes. Whether you have to send emails, visit websites, or going

  • through a ton of spreadsheets and PDFs, these jobs use laptops and desktop PCs

  • as their primary tool. And sometimes using a computer means spending hours

  • doing tasks that require a bunch of mindless clicking and typing.

  • If you don't have an intern to shuffle this work off to, you should learn to code so

  • that you could program to computer to do these task for you. Or if you're the

  • intern, you should learn to code so that you can program the computer to do these

  • task for you. So how is this course is different from all the other online

  • programming courses? Well, I wrote Automate the Boring Stuff with Python

  • for people who wanted to get up to speed making small programs that do practical

  • tasks as soon as possible.

  • You don't need to know sorting algorithms or object oriented

  • programming paradigms, so this course skips all of the computer science and

  • concentrate on writing code that get stuff done.

  • But if you are a computer science student for budding software engineer,

  • this course will be a good first step to develop your toolkit of programming

  • skills. This course uses the Python programming language. Python is the best

  • first language to learn. Many universities are switching their

  • computer science curriculum away from Java and to Python. It has a simple

  • syntax and a gentle learning curve, but it's still a powerful language used in

  • the real world.

  • Google, NASA, Yahoo, YouTube and even non-technology companies like JPMorgan Chase

  • or Industrial Light and Magic, all used Python. So learning to code can increase

  • your productivity but it's also a fun, creative skill and unlike other creative

  • skills or hobbies, if you have a computer there's nothing else to buy in

  • order to write code. You don't have to buy paint or yarn or power tools. All you

  • need is some free software called the Python interpreter.

  • Sound good? Let's get started. Right now.

  • Open a web browser and go to python.org. You'll need to download and install

  • Python for your operating system. This is slightly different on Windows, Mac, and

  • Linux, so consult the course notes for specific instructions. The one thing you

  • need to know is that you should download a version 3 Python, like Python 3.5 and not a

  • version 2 Python, like Python 2.7. When we say "Python" we usually mean either the Python

  • interpreter software that you've just downloaded installed or the Python

  • language. Python (the software) comes with an editor program that you type your

  • Python (the language) code into. The editor is called IDLE. Consult the

  • course notes for how to start up IDLE on your operating system. Beginning in the

  • next lesson we'll start writing code using it. I highly recommend that you

  • have IDLE open and follow along with the videos by typing the examples into it.

  • Don't just sit and watch the videos. It's easy to passively watch the videos and

  • think you understand the concepts. Typing the code build your muscle memory and

  • forces you to see if you can get the code working. One last thing that you

  • should know from the start:

  • Half of the software engineers day is spent googling for information. Programming can be

  • complicated and no one can keep all this information in their head. So don't feel

  • bad about constantly looking stuff up on the internet. That's exactly what

  • professional software developers do every day. So if you get an error message

  • and you have no idea what it's talking about, a good starting point is copying

  • and pasting this message into a search engine.

  • The first 3 results will probably be to a website called Stack Overflow, which is a great

  • question and answer site. So before asking people for an answer,

  • try to find the answer yourself on the web. One, this will almost always be

  • faster because, two, other people have probably had your question and already

  • had answered.

  • But when you do ask questions, provide as much detail as possible

  • Here's a few things to keep in mind. Explain what you're trying to do, not

  • just what you did. Your helper can then tell you if you're on the wrong track.

  • If you get an error message, specify the point at which the error happens. What

  • line number does it happen on? Does the error happen every time or does it just

  • happen randomly sometimes?

  • Copy and paste the entire error message and your code to a pastebin site, like

  • pastebin.com or gist.github.com. These websites will give you a link

  • to your text which makes it easy to share with other people.

  • Explain what you've already tried to do to solve your problem.

  • This trims down the list of possible causes and tells people that you've already put

  • some work into figuring things out on your own. List the version of Python

  • you're using. Also, say if you're running Windows, Mac, or Linux and what version

  • you're running, like Windows 7 or Mavericks 10.9.2.

  • Asking effective questions and knowing how to find answers are invaluable tools

  • on your program journey. Let's begin!
