Scopes. Variables are stored in scopes (also called namespaces). There are two main scopes in Python the global scope and the local scope. Scopes may be nested. Recursion. A function can call itself and if it does, it s called recursion. Everything you can do with recursion can also be done by loops, but sometimes a recursive function is more readable. Functional programming. Python has some facilities for programming in a functional style. Among these are lambda expressions and the map, filter, and reduce functions.

This technique works well if you re passing programs between your own machines or servers, or if you re distributing your programs to other developers. As long as the other users and machines have the same Ruby libraries or gems that your program uses, your program should run fine. This is one benefit of interpreted languages over compiled languages. If the same version of the Ruby interpreter is available on a different platform, it should run the same programs that your Ruby interpreter does. With compiled code (code that is specifically compiled down to machine code for a specific platform), it is not the case that it will run identically on all platforms; in fact, it usually won t! What if you want to distribute your Ruby program to people who aren t au fait with the Ruby interpreter Depending on the target operating system (that is, the operating system the user is running), there are several ways to make deploying Ruby applications simpler.

Every time the thread created in this example prints a number to the screen, it stops itself. It can then only be restarted or resumed by the parent program calling the run method on the thread, like so:

If you ve done your work well in the story template, you anticipate questions by tailoring the presentation to the audience and addressing the questions they re wondering as you complete each of the acts and scenes. Opening the oor to Q & A is important even if you ve covered everything, people who are making decisions will still want to ask questions so that they feel like they ve participated in the experience. Depending on how you planned it into your storyboard, you might open up the oor to conversation from the very start in Act I, at the end of the rst and second Key Point sections, or after you conclude your prepared remarks and invite audience comments. In some instances, you might even want to purposely leave a few questions unanswered so that the audience will be sure to ask them and engage you in the Q & A. If you re speaking to a large audience and take a question, restate the question before you answer it to make sure that everyone in the room hears it. If someone asks a question about a particular slide, refer to the printed storyboard for the corresponding slide number, and then type the number of the slide and press Enter to go directly to that slide. If you want to show a slide that relates to a general question from one of the Act II scenes, type the number of whichever Act II slide corresponds with the question and press Enter. If you have extra material that didn t t into the Act II slides but you think you might still be asked about it, add the extra slides to the end of the presentation and refer to them if some questions relate to them.

A thread can also tell the Ruby thread scheduler that it wants to pass execution over to another thread. The technique of voluntarily ceding control to another thread is often known as cooperative multitasking, because the thread or process itself is saying that it s okay to pass execution on to another thread or process. Used properly, cooperative
