Filter list respecting seniority & no more than 3 same number

[Azerate]

Alright ! so a little update :)

I believe i managed to understand most of the content of the code you wrote & tweaking it best i can with the limited knowledge i got in python

I am confused about the line 9 which is 'assignments = [ ]'

I believe it will refer to the list of the assigned week.
Can i get few pointer on how i am supposed to build that list?
I guess it will need to be built from the result of the code you wrote right?

Also, what is the reference to week_num, what does it do and where does it come from, is it built-in into python or something ?

from collections import OrderedDict

preferences = OrderedDict([('Jean', (1, 2, 3, 4, 5)), ('Claude', (1, 2, 3, 4, 5)),  ('Van', (1, 2, 3, 4, 5)),
                     ('Kung', (1, 2, 3, 4, 5)), ('Fu', (1, 2, 3, 4, 5)), ('Panda', (1, 2, 3, 4, 5)),
                     ('To',(1, 2, 3, 4, 5)), ('Much', (1, 2, 3, 4 , 5)), ('Absolver', (1, 2, 3, 4, 5))])

weeks = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30,
         31, 32,33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52]

assignments = [ ]

tracking = {week_num: 0 for week_num in weeks}
assignments = [ ]
for preferences in [ ]:
    assignments.append([ ])
    for week_num in preferences:
        if tracking[week_num] < 3:
            assignments[-1].append(week_num)
            tracking[week_num] += 1
            if len(assignments[-1]) == 2:
                break

for key, value in assignments.items() :
    print (key, value)
