I know this can be done with lists, but I'm just trying to figure out how to do this with dictionaries.
Basically, it'll go like this:
dict1 = {'a': 10, 'b': 12, 'c': 9}
dict2 = {'a': 10, 'b': 3, 'c': 9}
def intersect(dict1, dict2):
combinDict = dict()
....
print(combinDict)
{'a': 10, 'c':9}
So I only want the keys with the same value added into a new dictionary.
Any help?
You want the intersection of the items:
dict1 = {'a': 10, 'b': 12, 'c': 9}
dict2 = {'a': 10, 'b': 3, 'c': 9}
print dict(dict1.viewitems() & dict2.items())
{'a': 10, 'c': 9}
For python 3 you just want to use items:
dict(dict1.items() & dict2.items())
dict1.items() & dict2.items() returns a set of key/value pairings that are common to both dicts:
In [4]: dict1.viewitems() & dict2.items()
Out[4]: {('a', 10), ('c', 9)}
Then we simply call the dict constructor on that.
