merging Python dictionaries

Question

I am trying to merge the following python dictionaries as follow:

dict1= {\'paul\':100, \'john\':80, \'ted\':34, \'herve\':10}
dict2 = {\'paul\':\'a\', \'joh         


        

Answer 1

In Python3.1,

output = {k:[dict1.get(k),dict2.get(k)] for k in dict1.keys() | dict2.keys()}

In Python2.6,

output = dict((k,[dict1.get(k),dict2.get(k)]) for k in set(dict1.keys() + dict2.keys()))
