Well, here's a real method I ran into a while back - with
.replace(origname, 'example'). Written by a perfectly able python
programmer in publicly released code:
def example_command(self, command, args):
args = ' '.join("'%s'" % arg for arg in args)
return 'example --example-dir=%s %s %s' % (self.example_dir, command, args)
What's wrong with it? Well, if you use unix, with no spaces in
directories and legal 'quote', you'll probably say "nothing". String
interpolating command calls makes for unnecessarily non-portable code.
Now, if subprocess could only start (optionally) taking unicode
arguments so I could actually get at my whole filesystem through it...
