How to merge similar items in a list

Question

I haven\'t found anything relevant on Google, so I\'m hoping to find some help here :)

I\'ve got a Python list as follows:

[[\'hoose\', 200], [\"Ba         


        

Answer 1

Blueprint:

result = dict()
for item in [[['hoose', 5], 200], [['House', 5], 200], [["Bananaphone", 5], 10], ...]:

   key = item[0] # ('hoose', 5)
   value = item[1] # 200

   if key in result:
       result[key] = 0
   result[key] += value

It might be necessary to adjust the code for unpacking the inner list items.
