Python Return Most Common Element

Question

I am trying to create a function that returns the most common element from an array it is passed. My code looks like this:

def get_classification(classes):
    from collections import Counter
    count = Counter(classes)
    return count.most_common()[0]

And it is properly returning the most common element. However, it returns it in the format element, count such as:

3.0, 2
2.0, 3
1.0, 3

I don't want it to return that tuple. I just need it to return the most common element. How is that possible?

I have tried the solution:

counts = numpy.bincount(classes)
final = numpy.argmax(counts)

return final

But that did not work for me either. Any advice would be greatly appreciated.

I was not able to get that solution to work for me, even after spending a half hour. @U9-Forward — artemis, Mar 06 '19 at 02:35
Understood, I will retry, thank you. I'm sorry for duplicating, I did see that post and try it but to no avail @U9-Forward — artemis, Mar 06 '19 at 02:37

You can use indexing again, to get the first element of the tuple:

def get_classification(classes):
    from collections import Counter
    count = Counter(classes)
    return count.most_common()[0][0]

print(get_classification([1, 3, 3, 1, 2, 1])) # ==> 1
