Small core, large library

Like Java, Python has a small compact core and a large, extensible library . Thus, much of what you will need to do has already been written and tested for you. Yourtask will be to write the code to glue those library components together, and to write new capabilities on an as-needed basis.

Let's Write a Program

Getting ready

Download and install the software

The first step is to go to (External Link) with your web browser. Download, and install the Python software using thedownload link that you will find there.

I'm going to assume that either you already know how to do this, or you can get help from a friend. In other words, I'm not going to try to explain how todownload and install the Python software.

Note: If you are working in an ACC computer lab on the Northridge campus, you don't need to download and install the Python software. It hasalready been installed. If you are working in an ACC computer lab on a different campus and you don't find the Python software, ask the lab manager to downloadand install it. If you are working on your computer at home, at some point you will need to download and install the Python software.

Starting the programming environment

As I mentioned earlier, all of my instructions will be based on the use of Python running on my Windows operating system.

However, as I also mentioned earlier, you have many choices for using Python. If you are running on some other platform, you will need to translate my instructionsfrom Windows jargon into the jargon of your platform.

Enough talk -- let's begin

Find the Start button on the task bar on your Windows desktop. Select

Start/All Programs/Python x.y

where x.y is the version of Python that you have downloaded and installed. At the time of this writing, I have version 3.4.1 installed on my computer, and theselection shows on the menu as Python 3.4.

What do you see?

When you make this selection, you should see a menu having at least the following five options :

  • IDLE (Python GUI)
  • Module Docs
  • Python (command line)
  • Python Manuals
  • Uninstall Python

The Python Manuals

Don't be bashful about selecting and reading the Module Docs and the Python Manuals. There is a wealth of information contained there, including a tutorial.

The library reference

A good way to get a feel for the breadth and power of Python is to select Python Manuals from the menu and then select the Library Reference link. (The Library Reference is also available online as of the time of this writing.)

Most of what you see there probably won't mean much to you at this point in time, but hopefully will be familiar territory after you complete this course.

IDLE (Python GUI)

Selecting IDLE (Python GUI) from the menu brings up a window titled "Python 3.4.1 Shell" on my computer. This is one of the interactive programming environments available with Python on MicrosoftWindows.

What does it look like ?

When you select IDLE (Python GUI) from the menu, you should see something like Figure 1 .

(Note to blind and visually impaired students: I don't know if you will find the Python Shell to be accessible. If not, don't worry. We will get to acommand-line version that should be accessible a little later.)

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
how did you get the value of 2000N.What calculations are needed to arrive at it
