Hey all, hopefully a simple question.
I'm writing a simple python tool that opens a file, and does something like
for line in file.readlines():
temp.write(line.doStuff())
However, I want to provide the option do this "in place", as in have the
destination file be the same as the source file. Currently, I am writing to
a temp file and then using "os.system('mv %s %s' % (dstfile, srcfile))" to
copy the destination file onto the soruce file. This is extremely ugly
though, and will only work on unix based systems (I'm guessing, unless
windows has mv too). Is there a more pythonic way to do this? Ideally I'd
like to change the file as I go through it and not deal with a second file
at all. That wouldn't have any atomicity though... What would be the most
pythonic+safest way to do this?
Thanks in advance
