Question

I am in B.Tech 1st year so Please suggest me a best book for C language(including basics because i don't no any thing related to C).

Answer 1

I have downloaded .py 2.7 from python.org when I go to start --> python 2.7 --> IDLE (Pythong GUI) I type this in:

x = 3 # Create variable x and assign value 3 to it
x = x * x # Bind x to value 9
print x
n = raw_input('Enter a number:')
print n
# print n/n

How do I make this run like the professor is doing at the 27.00 minute mark in the following video: http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/video-lectures/lecture-2/

Answer 3

I'm an experienced programmer with over 26 years of software development and even I had problems figuring out how to run a script. Let me take you step-by-step how this is accomplished:

(I'm running windows so please forgive the windows centric dialog)

1: go to your start menu, (all programs) locate your python install folder.
and click on it. (you'll get a drop down of the installed programs)

2: click on the IDLE(Python GUI) option/program to run IDLE

3: using the file menu option in the upper left of the python engine, click on the "New Window" option.

4: type or copy your script and save your file (using again the file/save or save-as option. Programming language interpreters are finicky be sure all your punctuation and indentation is how you intend it to be.

Note:
Don't forget when you are given the option to save your script, name it with the file extension of .py this allows your file system to understand what type of file this is and will automatically run the appropriately bound application when you double click it from the file browser.

5: to run your script you will see in the idle editor the "Run" option in between "Format" and "Options" menus. click this you will see a drop-down with "Run Module"
if you just want to check syntax of your script without running it use the "Check Module" option

if you try to run the script and have not yet saved it, IDLE will give you the opportunity to save the script before running it.
