v5 v6 1 1 Prerequisites: [wiki:SoftwareOverviewControl Control Systems Overview] 2 2 3 = Lesson 1: 3 = Lesson 1: Getting Started = 4 4 If you want to tell a computer to do something, you have to communicate with the computer in a programming ''language''. When we say language, we mean it. A language has words and grammar and everything else, just like French. 5 5 6 Computers, despite what you may think, are dumb. They do only exactly what you tell them to, and don't guess or interpret. If say to your Mom or Dad "Hey, can you bring me that thing?", there's a (slim) chance they may bring you the right "thing". A computer wont. Ever. Just a cold, unfeeling "'''ERROR'''". 6 Computers, despite what you may think, are dumb. They do only exactly what you tell them to, and don't guess or interpret. If say to your Mom or Dad "Hey, can you bring me that thing?", there's a (slim) chance they may bring you the right "thing". A computer wont. Ever. Just a cold, unfeeling "'''ERROR'''". A programming language is very precise, and to tell a computer what you want, you have to be precise too. In this training session, we'll introduce programming to you, and make some things work. You know, those ''things''. 7 7 8 8 Hang on, it gets harder from here. 9 9 10 (A quick note...If you know all this already and are getting bored , CONGRATULATIONS!

Some are created because they're better for solving certain problems, others because people are bored and want to try something new. Python has been around for a while, and its pretty popular because its easy to use. The team uses Java to control the robot but that language is a little trickier. We'll get to that one later once you get a handle on the basics.12 We'll be starting with a programming language called [https://www.python.org/ Python], specifically Python 3.

Now on that site, highlight all the text in the central area and hit back space (this we'll clear out all the sample code. We'll call this "clear out the test code" from now on. Then highlight the code above, and click copy, and paste the two lines above into that editor. Then click "Execute".
