Which is the best way to extend a dictionary with another one? For instance:
>>> a = { "a" : 1, "b" : 2 }
>>> b = { "c" : 3, "d" : 4 }
>>> a
{'a': 1, 'b': 2}
>>> b
{'c': 3, 'd': 4}
I'm looking for an operation to obtain this avoiding for loop:
{ "a" : 1, "b" : 2, "c" : 3, "d" : 4 }
I wish to do something like:
a.extend(b) # This does not work
