urlgrabber is a pure python package that drastically simplifies the fetching of files. It is designed to be used in programs that need common (but not necessarily simple) url-fetching features. It is extremely simple to drop into an existing program and provides a clean interface to protocol-independant file-access. Best of all, urlgrabber takes care of all those pesky file-fetching details, and lets you focus on whatever it is that your program is written to do!

urlgrabber came into existence as the part of yum that downloads rpms and header files, but it quickly became clear that this is a general problem that many applications must deal with.


Using urlgrabber, data can be fetched in three basic ways:
urlgrab(url) copy the file to the local filesystem
urlopen(url) open the remote file and return a file object
urlread(url) return the contents of the file as a string
When using these functions (or methods), urlgrabber supports the following features:
