Vote count:

0

e.g

data = [ (item1, ('1-jan ,45)) , (item2, ('21-jan',65)), (item1, ('21-jan',48))]

I like something like:

result = [ (item1, [('1-jan ,45),('21-jan',48)]), (item2, [('21-jan',65)])]

to be precise I need final outcome

result = { item1: ('1-jan:45,'21-jan':48)), item2: ('21-jan':65)]
