Help with dates

[Angelo Secchi]

Hi,
I have a dictionary, data, with the following structure:

data['III']

[['18-07-1994', '283.000000', '292.500000', '27712168.000000']
['19-07-1994', '292.000000', '294.500000', '2492106.000000']
['20-07-1994', '294.000000', '294.500000', '4881451.000000']
['21-07-1994', '292.000000', '291.000000', '2183402.000000']
['22-07-1994', '293.000000', '291.000000', '889050.000000']
['25-07-1994', '293.000000', '292.000000', '657931.000000']]

and I would like to create a "sort" of daily increments of, for example,
the second column (ex. 292-283). I say "sort" since I do not need to
consider week ends (i.e. I can consider them as one day) but I would
also like to check if, in my database, there are big time jumps and
possibly discard corresponding increments. Where should I look for
hints in how to solve this task?

Thanks a lot,

angelo

angelo,
Do you want to sort within one key's list/value? Would it be
better to have a key like ('III','18-07-1994') with
a value ('283.000000', '292.500000', '27712168.000000')? 'not sure
I understand what you're doing.
