I just want to enter integrate these two commands from cmd and use them in a python script, but I'm novice in both programming and python. How I can achieve this?
cd C:\
python dumpimages.py http://google.com C:\images\

2Incidentally - my telepathic spider-sense is telling me you might be trying to save images from a webpage. Have you considered using GNU wget for that?Li-aung Yip– Li-aung Yip2012-04-21 12:10:43 +00:00Commented Apr 21, 2012 at 12:10

I'm just trying to download changing images whose url is hidden. It's not a lot of pictures on the page, so I found this script. stackoverflow.com/questions/257409/…. More than needed, but it works.geekchap– geekchap2012-04-21 12:28:27 +00:00Commented Apr 21, 2012 at 12:28

Note that exec() will also work but it is deprecated in favour of os.subprocess.
Further to my comment above, if all you want to do is retrieve images from a webpage, use GNU wget with the -A flag:
wget -r -P /save/location -A jpeg,jpg,bmp,gif,png http://www.domain.com

Oh nice, I shall try this now! Thanks!

Note: the
-r flag is for 'recursive' - probably only need -p for page display prerequisites. (Consult man wget for more information.)I suspect the cd C:\ is not necessary, and once that's gone all you seem to be asking for is a way to launch a python script.
Perhaps all you want is to modify saveimage.py so that it has the hard-coded arguments you want? I don't know what that script is--maybe you can tell us if it's important or you aren't allowed to modify it.

It's Greg Hewgill's script from here: stackoverflow.com/questions/257409/… Trying to download images from a hidden url. There's only one or two pictures on the page, so I'm using this script because it was quick.

I think you are looking for sys.argv
Try:
import sys
print(sys.argv)
on top of your saveimage.py.
It should print something like:
['C:\saveimage.py', 'http://google.com', 'C:\images\']
You see, sys.argv is a list of strings. The first item is the name of the script itself, the others are the parameters.
Since lists are 0-based, you can access the i-th parameter to the script with sys.argv[i]

Thanks, it's on top of the script already. I'm just trying to combine two scripts into one.
