   If you want a command line script, is there a better way to handle the input argument than this?

   #! /usr/bin/python
   # Usage:
   # rot13.py ‘Hello, my name is Bob!’
   import sys
   import codecs
   data_to_rot13 = str(sys.argv[1:])
   rot13ed_data = codecs.getencoder(‘rot13’)(data_to_rot13)[0]
   print rot13ed_data

   Also, this live preview thing is neat. Is that a plugin?

   Python rocks my friend…thanks for convincing me. Used SWIG for the first time in the last few days…check it out.

   data_to_rot13 = str(sys.argv[1:])[/quote]

   First, str(some_list) applied to a list will get you the repr of it:

   >>> str([‘a’, ‘b’])
   “[‘a’, ‘b’]”

   The correct way is ‘ ‘.join.

   Even so, I generally use optparse for such things, even if I’m not going to have options, unless it’s a one-off script that I don’t care about.

   import optparse
   parser = optparse.OptionParser(usage=’%p “Hello, my name is Bob!”‘)
   opts, args = parser.parse_args()
   data_to_rot13 = ‘ ‘.join(args)

   The advantage of this is that I can easily add options later.

   Aye. It’s called Live Comment Preview.

   It’s even shorter in vim: g?G
