Question

I need to write a function that returns true if the dictionary has duplicates in it. So pretty much if anything appears in the dictionary more than once, it will return true.

Here is what I have but I am very far off and not sure what to do.

d = {"a", "b", "c"}

def has_duplicates(d):
    seen = set()
    d={}
    for x in d:
        if x in seen:
            return True
        seen.add(x)
    return False

print has_duplicates(d)

Answer 1

If you are looking to find duplication in values of the dictionary:

def has_duplicates(d):
    return len(d) != len(set(d.values()))

print has_duplicates({'a': 1, 'b': 1, 'c': 2})

Outputs:

True
