POLearning the Python Thread Module
text
Body
copied!<p>I am trying to learn more about the thread module. I've come up with a quick script but am getting an error when I run it. The docs show the format as:</p> <pre><code>thread.start_new_thread ( function, args[, kwargs] ) </code></pre> <p>My method only has one argument.</p> <pre><code>#!/usr/bin/python import ftplib import thread sites = ["ftp.openbsd.org","ftp.ucsb.edu","ubuntu.osuosl.org"] def ftpconnect(target): ftp = ftplib.FTP(target) ftp.login() print "File list from: %s" % target files = ftp.dir() print files for i in sites: thread.start_new_thread(ftpconnect(i)) </code></pre> <p>The error I am seeing occurs after one iteration of the for loop:</p> <blockquote> <p>Traceback (most recent call last): File "./ftpthread.py", line 16, in thread.start_new_thread(ftpconnect(i)) TypeError: start_new_thread expected at least 2 arguments, got 1</p> </blockquote> <p>Any suggestions for this learning process would be appreciated. I also looked into using threading, but I am unable to import threading since its not install apparently and I haven't found any documentation for installing that module yet.</p> <p>Thank You!</p> <p>There error I get when trying to import threading on my Mac is:</p> <pre><code>>>> import threading # threading.pyc matches threading.py import threading # precompiled from threading.pyc Traceback (most recent call last): File "<stdin>", line 1, in <module> File "threading.py", line 7, in <module> class WorkerThread(threading.Thread) : AttributeError: 'module' object has no attribute 'Thread' </code></pre>
