Package seqdict
seqdict - single value dictionary
msedict - multiple value dictionary
The Python built-in dictionary has no reliable sequence order because
of performance reasons.
The two new dictionaries introduced here keep their entries in sequence.
* seqdict keeps one value for one key
* mseqdict keeps multiple values per key and is the closest emulation
of areal world dictionary.
As the sequential dictionary is a combination of a list and a dictionary
you can do most operations defined with lists as well and much more.
Now you can slice, add, sort with dictionaries. The functional
operations
map, filter, reduce are implemented as well. Use a dictionary like a
stack
with push and pop. Split it, reverse it and swap keys and values.
A small tutorial is provided as HTML and Postscript Source and is
subject
to become improved some other day.
I think both dictionaries are candidates for the python standard
library.
Use the seqdicts to emulate a printed dictionary. Use them for workinse
them for working with csv-tables. Keep parsed code in a seqdict, modify
it
and write it back ...
