Since I grabbed the python tar file from python.org, do I then assume that readline is not included in the python source distribution? if so, where would I find it. If not, what different build instructions do I need to follow to make it build with readline? -- David Bear -- let me buy your intellectual property, I want to own your thoughts --

For instance, to replace lines 3 to 7 (starting at zero) you could assign a list (containing the replacement lines) to a "slice" of the list of lines: lines[3:8] = replacement_lines Where replacement_lines is a list containing the replacement lines. There's a lot more to this, read up on python's lists. To convert the list back into one string use the join() method; if you kept the line endings, s = "".join(lines) or if you threw them away, s = "\n".join(lines) Python has standard modules for sha-1 digest, sha, and zlib compression, zlib. See http://docs.python.org/lib/lib.html HTH, enjoy, ~Simon

[big snip] This statement was given in the context of Windows and Linux, and I've precious little experience doing anything on Windows. So I won't challenge it in the least, and in fact do not doubt it. But taken out of that context, I'll challenge it. I was first exposed to Python about five or six years ago--my boss asked me to consider it. What I found was that the current version of Python was V2.2, but newest version (that I could find) that ran on VMS was V1.4. I decided to stick with Perl, which provides excellent support for VMS. Now that I no longer need to worry about VMS, I prefer Python. Quite a bit. /Dan

Help with arrays of strings
by Jon Smirl July 31, 2006

July 31, 2006

I only have a passing acquaintance with Python and I need to modify some existing code. This code is going to get called with 10GB of data so it needs to be fairly fast. http://cvs2svn.tigris.org/ is code for converting a CVS repository to Subversion. I'm working on changing it to convert from CVS to git. The existing Python RCS parser provides me with the CVS deltas as strings.I need to get these deltas into an array of lines so that I can apply the diff commands that add/delete lines (like 10 d20, etc). What is the most most efficient way to do this? The data structure needs to be able to apply the diffs efficently too. The strings have embedded @'s doubled as an escape sequence, is there an efficient way to convert these back to single @'s? After each diff is applied I need to convert the array of lines back into a string, generate a sha-1 over it and then compress it with zlib and finally write it to disk. The 10GB of data is Mozilla CVS when fully expanded. Thanks for any tips on how to do this. Jon Smirl jonsmirl(a)gmail.com

under naming
by David Bear July 31, 2006

July 31, 2006

I must have missed reading something important about naming conventions. I have found that if I have a python module where I have an identifier named with a beginning underscore that I cannot use from module import * to make that name available in another module. for example, module A _myvar = 'a local var' module B from A import * _myvar -- is not available. Is this in a pep somewhere ? -- David Bear -- let me buy your intellectual property, I want to own your thoughts --
