All errors during a retry-enabled request should be wrapped in urllib3.exceptions.MaxRetryError, including timeout-related exceptions which were previously exempt. I am trying to download files from a website using urllib as described in this thread: link text import urllib urllib.urlretrieve ('http://www.example.com/songs/mp3.mp3', 'mp3.mp3') I am able to download the files (mostly pdf) but all I get… A simple workaround for this would be to do one or more of: a) define the 'timeout' attribute as socket._Global_Default_Timeout at class-level b) initialize the 'timeout' attribute on urllib2.Request.__init__() With the OP's permission I am now filing a public bug with a patch, with the intent to submit the patch ASAP (in time for MvL's planned April security release of Python 2.5).

The Python support for fetching resources from the web is layered. urllib2 uses the httplib library, which in turn uses the socket library. As of Python 2.3 you can specify how long a socket should wait for a response before timing out. This can be useful in applications which have to fetch web pages. urllib.request.install_opener (opener) ¶ Install an OpenerDirector instance as the default global opener.

Purpose: A library for opening URLs that can be extended by defining custom protocol handlers. Available In: 2.1 The urllib2 module provides an updated API for using internet resources identified by URLs. It is designed to be extended by individual applications to support new protocols or add The following are code examples for showing how to use urllib2.Request().They are from open source Python projects. You can vote up the examples you like or vote down the ones you don't like.

This section covers the basics of how to install Python packages.. It’s important to note that the term “package” in this context is being used as a synonym for a distribution (i.e. a bundle of software to be installed), not to refer to the kind of package that you import in your Python source code (i.e. a container of modules). How to write to File Using Python? In order to write into a file in Python, we need to open it in write 'w', append 'a' or exclusive creation 'x' mode. We need to be careful with the 'w' mode as it will overwrite into the file if it already exists. All previous data are erased. File Handling File handling in Python requires no importing of modules. File Object Instead we can use the built-in object "file". That object provides basic functions and methods necessary to manipulate files by default. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command: % gpg --verify Python-3.4.0.tgz.asc
