Python: get numerical parameter from cgi.FieldStorage

[Giles]

Essentially I'm working on a gallery script (which I'm calling view_image.py), and I get the number of the image to display from the url via cgi.FieldStorage. I'm currently using

source = cgi.FieldStorage()
image_id = source['image_id'].value

So if I navigate to view_image.py?image_id=1001, that'll give me

image_id='1001'

Unfortunately that means that image_id is a string, and I need to be able to manipulate it numerically, so I need it as an int instead. I'm sure it must be possible to get a url parameter as a numeral, but I've yet to find anything on google. Does anyone have any ideas?

Thanks for taking the time to look at this

you can turn it into integer,eg image_id=int(image_id)

Awesome. Thanks very much.
