[Tutor] Python and PHP config files

[Lloyd Kvam]

An alternative approach would be to put the config information into a
dictionary.  Picking up from your code:
	...
	config = datafile.readlines()
	config_dict = {}
	for con in config:	#line by line
		name,value = con.split('=')	#split as Kalle did
		config_dict[name] = value
	...

now
	db = config_dict["db_name"]

When I can, I like to save my config info directly in a dictionary that I
simply import.
