Preface

This module is one in a collection of modules on Python designed for teaching ITSE 1359 Introduction to Scripting Languages: Python at Austin Community College in Austin, TX. It provides an introduction to the use of scripts, and ofnecessity will depart from the interactive mode used in previous modules.

Viewing tip

I recommend that you open another copy of this module in a separate browser window and use the following links to easily find and view the Figures and Listings while you are reading about them.

(Note to blind and visually impaired students: all of the Listings in this module are presented in plain text format and should be accessible using anaudio screen reader or a braille display. However, there are a couple of bitmap images that may not be accessible.)

Introduction

This module provides an introduction to the use of scripts, and of necessity will depart from the interactive mode used in previous modules.

It will be necessary for me to get into a small amount of system stuff that really has nothing in particular to do with Python programming. Rather, it willinvolve getting your computer set up for using scripts with Python.

Up to this point in this collection, I have concentrated on the interactive programming capability of Python. This is a very useful capability that allows you to typein a program and to have it executed immediately in an interactive mode. But, interactive can be burdensome. By now you may have realized that you sometimes find yourself typing the same thing over and over. That is where scripts are useful.

Important characteristics of scripts

Scripts are reusable

Basically, a script is a text file containing the statements that comprise a Python program. Once you have created the script, you can execute it over andover without having to retype it each time.

Scripts are editable

Perhaps, more importantly, you can make different versions of the script by modifying the statements from one file to the next using a text editor. Then youcan execute each of the individual versions. In this way, it is easy to create different programs with a minimum amount of typing.

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.

what is the application of nanotechnology?
Stotaw
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
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
