We don't know what they are. They could be any integer.

Executable Code Warning

Let's not worry why I picked those. They're actually wisely chosen, as you will see in a minute.

Let's say that I make a mistake.

We would go back to the loop test and check the test expression again.

And so whereas here would be adding two lists together, we're just returning the value that it finds in these if statements at the end. So this is where actually we run the code.

The easiest way to demonstrate this is a little bit of JavaScript.

Narrator Now we're ready for our first quiz about append, plus, and len.

line of the program through the debugger.

Here is one way to implement this.

When we come back from the procedure, so once we get to here, we return.

Let's make this grid cell red over here as well.

Okay. So, but it's indeed a version of Python written in Python.

So here's my solution for problem 4.6, the CS215.

Please fill in the missing code over here.

Let's see if you're getting the hang of this. Here's a little quiz.

That's 20 21, 22, and the print statement is 23.

It should be an optional flag, so it has to have a default value of the bearing noise being on.

You can easily do that by going into a text editor and changing the code.

I can then apply an additional scale, rotate and translate. In this case I just want to rotate.

Here's a small list with the elements 0, 1, and 1.

So that's what's happening in this marked component.

Alright. So now we know how to parseJSON data. How do we actually retrieve that from our server?

Line end style

The only problem with delta debugging is that the test function is somewhat elaborate.

To ease working in the shell environment, the following constants are defined

What break does is jump out of the loop, so we don't execute the more code, we don't execute the test expression again.

And you solved the estimation problem.

And it really overcomes some basic barriers in both of the 2 previous methods.

It can also be a more complicated expression, doing some arithmetic.

Okay. Here we are in our get coords function.

What if we just say we don't know what n is. Someone is going to tell us n later.

Fifth, debugging tools.

The way that we're going to score this quiz is instead of you telling me a mathematical expression for this function,

Our researchers are interacting with this data by injecting bacterial code, which are computer programs, that allow these creatures to grow over time.

We're much better off having parameters with names like page that remind us what they mean.

So let's take a look at some of the sample codes and we'll try to execute it.

That is an amazing small amount of code for something that's amazingly powerful.

Narrator So, now we're ready for a quiz about aliasing.

This algorithm is beautiful, and you can implement it in less than 10 lines of program code.

The way I'm going to do it is to use these numbers here and run through those backwards.

lines of code with the for loop, you instead have one line of code and what this

And I tried that and I get it running 34 times faster

We write our code up here, when we click run... ... it will run the code, we'll see the output.

This took 16 expansions to get to this point.
