    <p>So I wrote this short script (correct word?) to download the comic images from explosm.net comics because I somewhat-recently found out about it and I want to...put it on my iPhone...3G.</p> <p>It works fine and all. urllib2 for getting webpage html and urllib for image.retrieve()</p> <p><strong><em>Why I posted this on SO: how do I optimize this code? Would REGEX (regular expressions) make it faster? Is it an internet limitation? Poor algorithm...?</em></strong></p> <p>Any improvements in speed or <strong><em>general code aesthetics</em></strong> would be greatly appreciated "answers".</p> <p><i>Thank you.</i></p> <p><i>--------------------------------CODE----------------------------------</i></p> <pre><code>import urllib, urllib2 def LinkConvert(string_link): for eachLetter in string_link: if eachLetter == " ": string_link = string_link[:string_link.find(eachLetter)] + "%20" + string_link[string_link.find(eachLetter)+1:] return string_link start = 82 end = 1506 matchingStart = """&lt;img alt="Cyanide and Happiness, a daily webcomic" src="http://www.explosm.net/db/files/Comics/""" matchingEnd = """&gt;&lt;/""" link = "http://www.explosm.net/comics/" for pageNum in range(start,start+7): req = urllib2.Request(link+`pageNum`) response = urllib2.urlopen(req) page = response.read() istart1 = page.find(matchingStart) iend1 = page.find(matchingEnd, istart1) newString1 = page[istart1 : iend1] istart2 = newString1.find("src=")+4 iend2 = len(newString1) final = newString1[istart2 +1 : iend2 -1] final = LinkConvert(final) try: image = urllib.URLopener() image.retrieve(final, `pageNum` + ".jpg") except: print "Uh-oh! " + `pageNum` + " was not downloaded!" print `pageNum` + " completed..." </code></pre> <p><i>By the way, this is Python 2.5 code, not 3.0 but you bet I have all the features of PYthon 3.0 greatly studied and played around with before or right after New Year (after College Apps - YAY! ^-^)</i></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
