In Perl, there is a module called "Tie::File". What it does is tie a list to each line of a file. Change the list, and the file is automatically changed, and on top of this, only the bits of the file that need to be changed are written to disk. At least, that's the general idea.
I was wondering if something roughly similar could be done in Python, or at the very least, if I can avoid doing what amounts to reading the whole file into memory, changing the copy in memory, and writing it all out again. -- http://mail.python.org/mailman/listinfo/python-list
