Let's first start with foo as we've just seen it.

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

That is, the same thing as before but now enclosed in double quotes.

Come back up here it's still greater than 0.

We run the whole thing, and now with every line the file name should be opened, line should be read, and the one, single executed line should be printed.

Notice that these three actions have no slack between them.

We see it prints January.

In this case, it's exampleForm, which is right here, so we would grab this entire form.

And when you view this image on your computer it actually is going to download and run that program.

The tool changer on this VF 2SS needs to be recovered

If they're exposed, they'll be executed.

You see the first tag is false, being executed, then quote is false, being executed, out being set to the empty string is being executed, and here now you can see the entire program one by one as it produces the output.

A subroutine called countdown takes an input x.

Let's assume that we have a line in our program and a number of runs.

And now for the answer c was a less than sign.

Here comes the answer to the quiz.

There's a big hit going down.

Then the list continues as long as it's not empty.

Therefore, if you can reproduce the input, you can also reproduce the execution.

Depending on whether a is less than 0 or not, it's going to either execute this line, or it's going to execute this line.

I learn nothing about the velocity, so it's still 0, just the way I initialized it.

So what we do is, we simply write an assert false in here, meaning that the assertion should now automatically fail, if this ever gets executed.

Now let's see what this looks like for foo with markup.

And when you view this image on your computer it actually is going to download and run that program.

And this is precisely this line, namely, quote not quote.

So it's not going to execute this.

I've got 1 1.

This statement is going to get executed once per node.

Only executables on local file systems are supported.

So again we say, in our hypothesis tag is being set and we use assert to check that.

By using the sys.settrace function, you can specify a function, here traceit, that it will be executed after every single line is executed in your program.

And all the people and I think there's a lot of people at TED who do things because even though there's not an immediate return on the investment because it will only really pay off when everybody else has done it they'll do it because they're the sort of person who just does things which would be good if everybody else did them.

No lyrics script is running.

This may not be as useless as you might think, since often you 'd want to end the loop using a conditional break statement instead of using the for truth expression.

It's amazing how much you can get done with just these conditionals.

This task will be executed at the specified intervals.

Let's just run this program to see what happens.

The only way out of poverty is through business enterprise.

It's still going to be in this else statement, but since it's greater than two, it's going to go into this internal if statement instead of this other else.

And there's a really wonderful experiment that was done that suggests that we really should go ahead and do this.

And it's what is the work you can't not do?

Now we're just going to print the number 3.

And again, it comes up with a number of interesting inputs.

I'd like it to do something for me but I don't know for sure that it's not malicious.

If none of these happens
