How can I combine dictionaries with the same keys?

Question

I have a list of dictionaries like so:

dicts = [
    {\'key_a\': valuex1,
     \'key_b\': valuex2,
     \'key_c\': valuex3},

    {\'key_a\': valuey1,
     \         


        

Answer 1

big_dict = {}
for k in dicts[0]:
    big_dict[k] = [d[k] for d in dicts]

Or, with a dict comprehension:

{k: [d[k] for d in dicts] for k in dicts[0]}
