| Here's most of what you'll need to handle dictionaries:
|
| d1 = {} # create empty dictionary
| d2 = {"one": 1, "two": "two", 3: "three"} # create and populate dictionary
| d3 = {1: 'spam', {'a': 'b'}} # nesting
| d2["two"] = 42 # adding, changing
| d3[1]['a'] = 'c' # changing value in nested dictionary
| x = d2['two'] # fetch using index
| y = d3[1]['a'] # fetch from nested dictionaries
| cnt = len(d2) # get no. of key/value pairs
| del d2[3] # remove key/value
| for k in d2.keys(): # loop over keys
| for v in d2.values(): # loop over values
| for k,v in d2.items(): # loop over key/value pairs
| d = d2.keys; d.sort() # get sorted list of keys
|

Thanks for the information. At least you weren't rude about it.
