I have two dictionaries, but for simplification, I will take these two:
>>> x = dict(a=1, b=2) >>> y = dict(a=2, b=2)
Now, I want to compare whether each key, value
pair in x
has the same corresponding value in y
. So I wrote this:
>>> for x_values, y_values in zip(x.iteritems(), y.iteritems()): if x_values == y_values: print 'Ok', x_values, y_values else: print 'Not', x_values, y_values
And it works since a tuple
is returned and then compared for equality.
My questions:
Is this correct? Is there a better way to do this? Better not in speed, I am talking about code elegance.
UPDATE: I forgot to mention that I have to check how many key, value
pairs are equal.

If you want to know how many values match in both the dictionaries, you should have said that :)
Maybe something like this:
shared_items = {k: x[k] for k in x if k in y and x[k] == y[k]} print(len(shared_items))
