问题 I was looking into python urllib2 download size question. Although the method RanRag or jterrace suggested worked fine for me but I was wondering how to use the urllib2.Request.get_header method to achieve the same. So, I tried the below line of code: >>> import urllib2 >>> req_info = urllib2.Request('http://mirror01.th.ifl.net/releases//precise/ubuntu-12.04-desktop-i386.iso') >>> req_info.header_items() [] >>> req_info.get_header('Content-Length') >>> As, you can see the get_header returned

问题 I created program that downloads web pages and processes them in multithreaded way (scraper). During the working of the program, the computer gets sleeps and enters into Stand-By mode. I try adding various workarounds - adding time.sleep(), writing to a temp file, writing to the console and none of this prevented entering Stand-By mode.
