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

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

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

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

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

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

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

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

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
