[Tutor] path to executing .py file
Hello everybody! I'm working on my code repository (svn) auto-backup script which get hotcopy of svn repository directory to a directory named by date in same location where script file is, it executed by a timer program every 00:00 clock. Everything works fine when I'm testing by double click it. But when auto execute it, I got unexpected behavior. The backup directory will be created under "C:\Documents and settings\username". I create backup directory by this way: os.mkdir(os.getcwd() + arch_dir) is there some way to get path to my executing script, so I can replaced "os.getcwd()" in above line? And I have another question, I've tried remove a copy of svn repository by calling shutil.rmtree(svn_repos_copy_dir) I got error "Access denied!" Is that mean my script has no power to delete it? Is there some way to give the right to do that? thanks tiefeng wu 2009-04-14 ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hi David!
My solution of your problem would be the following:
>>> infile = open('step2', 'r')
>>> str = infile.read()
>>> infile.close()
>>> outfile = open('pyout', 'a')
>>> outfile.write(str.replace('\n', ' -d\n'))
>>> outfile.close()
hope helped
cheers!
