Dictionary & data

[kbass]

I have retrieved data from a database and I want to place this data into a
dictionary or something like a HashMap (in Java). Can someone point me to
an example?

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

It's probably a good idea to work your way through the tutorial here:

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