Question

I am quite new to python…

 import sys, os, time, py4chan, urllib from urllib2 import urlopen, URLError, HTTPError

 def refreshthread(boardin,no):
     global thread
     global topic
     board = py4chan.Board(boardin)
     thread = board.getThread(int(no))
     topic = thread.topic
     time.sleep(2.5)

 def dlfile(url, folder):

     try:
         f = urlopen(url)

         with open(folder + "/" + os.path.basename(url), "wb") as local_file:
             local_file.write(f.read())
             print "Downloaded to " + str(folder + "/" + os.path.basename(url)) 

     except HTTPError, e:
         print "HTTP Error:", e.code, url
     except URLError, e:
         print "URL Error:", e.reason, url

 def getsize(uri):
     file = urllib.urlopen(uri)
     size = file.headers.get("content-length")
     file.close()
     return str(int(size) / 1024)

 def main():
     boardtag = str(raw_input("Board: "))
     threadno = int(raw_input("Thread id: "))
     folder = str(raw_input("Save to folder: "))
     print "Getting thread information..."
     refreshthread(boardtag,threadno)
     print "Subject: " + topic.Subject
     while(True):
         if not os.path.exists(folder): os.makedirs(folder)
         refreshthread(boardtag,threadno)
         for imgurl in thread.Files():
             if imgurl is not None and not os.path.exists(folder + "/" + os.path.basename(imgurl)):
                 print "A wild image appears! " + "(" + getsize(imgurl) + "kb)" 
                 dlfile(imgurl,folder)
             else:
                 pass

 if __name__ == '__main__':
     main()

I coded this on linux and it runs perfectly, but if I run this on windows, I get this error:

TypeError: __init__() takes exactly 4 arguments (2 given)

Which is quite strange as I haven’t defined init.
Could this be an init from another module?

The py4chan module seems to work fine if i code other scripts.
Both machines have same python version too.

EDIT(Full error):

Getting thread information...
Traceback (most recent call last):
  File "4chan.py", line 59, in <module>
    main()
  File "4chan.py", line 46, in main
    refreshthread(boardtag,threadno)
  File "4chan.py", line 15, in refreshthread
    board = py4chan.Board(boardin)
TypeError: __init__() takes exactly 4 arguments (2 given)

*Edit:*Okay, i had two different modules of the same name. All working now.
I shouldn’t be allowed on this website.

Answer 1

The py4chan.Board class needs to be constructed with 3 arguments, not 1. This line in the refreshthread function:

board = py4chan.Board(boardin)

Should look something this:

board = py4chan.Board(base_url, post_url, filesize)
