Looks like each item is:
- a list of 1 or more integers, in a comma-delimited list
- a slash
- a word composed of alpha characters
And the whole thing is a list of items in a comma-delimited list
Now to implement that in pyparsing:
>>> data = "12560/ABC,12567/BC,123,567,890/JK"
>>> from pyparsing import Suppress, delimitedList, Word, alphas, nums, Group
>>> SLASH = Suppress('/')
>>> dataitem = delimitedList(Word(nums)) + SLASH + Word(alphas)
>>> dataformat = delimitedList(Group(dataitem))
>>> map(tuple, dataformat.parseString(data))
[('12560', 'ABC'), ('12567', 'BC'), ('123', '567', '890', 'JK')]
