Need help specifying a ending while condition
- by johnthexiii
I have written a Python script to download all of the xkcd comic images. The only problem is I can't tell it to stop when it gets to the last one... Here is what I have so far.
import re, mechanize
from urllib import urlretrieve
from BeautifulSoup import BeautifulSoup as bs
baseUrl = "http://xkcd.com/1/" #Specify the first comic page
br = mechanize.Browser() #Create a browser
response = br.open(baseUrl) #Create an initial response
x = 1 #Assign an initial file name
while (SomeCondition):
soup = bs(response.get_data()) #Create an instance of bs that contains the response data
img = soup.findAll('img')[1] #Get the online file path of the image
localFile = "C:\\Comics\\xkcd\\" + str(x) + ".jpg" #Come up with a local file name
urlretrieve(img["src"], localFile) #Download the image file
response = br.follow_link(text = "Next >") #Store the response of the next button
x += 1 #Increase x by 1
print "All xkcd comics downloaded" #Let the user know the images have been downloaded
Initially what I had was something like
while br.follow_link(text = "Next >") != br.follow_link(text = ">|"):
but by doing this I actually send skip to the last page before the script has a chance to perform the intended purpose.
