click the PLAIN TEXT header for copy-pasteable version

  1. #!/usr/local/bin/python
  2.  
  3. author = {"php":"Rasmus Lerdorf",\
  4.     "perl":"Larry Wall",\
  5.     "tcl":"John Ousterhout",\
  6.     "awk":"Brian Kernighan",\
  7.     "java":"James Gosling",\
  8.     "parrot":"Simon Cozens",\
  9.     "python":"Guido van Rossum"}
  10.  
  11. langs = author.keys()
  12. langs.sort()
  13.  
  14. for language in langs:
  15.     print language,"is the child of",author[language]

You can also define the Python ksort() function similar to that found in PHP:

  1. def ksort(d, func = None):
  2.     keys = d.keys()
  3.     keys.sort(func)
  4.     return keys
  5.  
  6. # example use, assume 'd' is a dictionary
  7. for k in ksort(d):
  8.     print k, d[k]

(example taken from TheScript forum)
