I have a question about how to have a script call other progs (ie Word, Excel) and executing them. Can anyone point me in the general direction?

I think that in Perl you use the ` ` and it executes the statement in the console. I am not sure but it might be similar in Phyton.

import os
os.startfile("c:/windows/notepad.exe")

now sane with that code. could i configure it a little to open like a webpage or a picture on a web page?

Of course not. Those are two separate things. Unless you have a shortcut file to a webpage or a picture, then change the link in my code to that shortcut.

Otherwise you'll have to use urllib2 and save, then open, the output.

(Toggle Plain Text)

import urllib2
import os

# load this image:
image_in = "http://us.i1.yimg.com/us.yimg.com/i/ww/beta/y3.gif"

# save it as:
image_out = "my_image.gif"

# prepare the opener for opening web pages
opener = urllib2.build_opener()

# load the image in to a string
page = opener.open(image_in) 
image = page.read()

# open the stream with binary mode enabled
stream = open(image_out, "wb") 
stream.write(image)
stream.close()

# open the image
os.startfile(image_out)

Firstly, bear in mind os.startfile is Windows specific (it won't work on Mac or Linux if you try to run your script there).

Sane: may be better if you mentioned it's win-only before you advocated its adoption.

No, if you want to open a webpage in a web browser in a cross-platform manner you use the webbrowser module:

(Toggle Plain Text)

import webbrowser
# open the webpage
webbrowser.open("http://google.com")
# open an image in the browser
webbrowser.open("http://www.google.com/intl/en/images/logo.gif")

as you can see, you use the same function for both - webbrowser.open.

How would you perform this in Linux?

Use os.environ['OS'] or os.name to determine if it's linux. Then os.system("command") with the appropriate command that would be used to execute the program via linux command line.

FYI, os.environ['OS'] doesn't work on my mac, while os.name does.
