I guess if you import enough libraries just about anything can be made into a one liner… if you have imported BeautifulSoup, re, requests, and sys, in python3 you can simply do:<\/p>\n

print(re.sub(r'^.*imgurl=([^&]+)&.*$', r'\\1', str(BeautifulSoup(requests.get("http:\/\/images.google.com\/search?num=50&hl=en&safe=off&site=&tbm=isch&source=hp&biw=1744&bih=1279&q=%s&oq=" % sys.argv[1]).text).find(href=re.compile("imgurl")))))<\/div><\/div>\n

To find the first hit on a google image search with argv[1]. Google will probably change their URL images later today and it’ll stop working, but I wanted this for a random task….<\/p>\n

E.g. “foo.py one+ring+to+bind+them” currently yields the URL for this beauty:<\/p>\n

\"\"<\/a><\/p>\n

Or you can wimp out and do it the ez way.<\/p>\n
