Invalid Syntax in Code

Question

I am having trouble with this bit of code.

print(\"The Overall Winner is,\", sorted(data, key=lambda(x,y): sum(n[1] for n in y), reverse=True),sum(event[1] for e         


        

Answer 1

Your problem is that you're using argument unpacking in the lambda while using Python 3. Instead of doing this:

lambda(x,y): sum(n[1] for n in y)

Do this:

lambda item: sum(n[1] for n in item[1])
