You might also take a look at the split method in the re module.  This 
will allow you to use regular expressions to chop up your data.

  >>> import re
  >>> import string
  >>> text = "name: John Doe, age: 29, Address: 1234 Main St."
  >>> pat = re.compile("[:,]")
  >>> fields=pat.split(text)
  >>> fields
  ['name', ' John Doe', ' age', ' 29', ' Address', ' 1234 Main St.']
  >>> d={} # make a new empty dictionary
  >>> # for each item in fields, collect the field name and data
  >>> for I in range(0, len(fields)-1, 2):
  ... 	d[string.strip(fields[I])] = string.strip(fields[I+1])
  ... 
  >>> d # show what we did
  {'Address': '1234 Main St.', 'age': '29', 'name': 'John Doe'}
  >>> 

Enjoy!
