Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

What is the problem statement?

#

Your code sums the elements in the list accurately so you might be misunderstanding the problem statement.

#

It says unique - do you need to ignore the duplicates?

no the answer would be 5

#

Ah, non-unique numbers aren't included at all.

#

No worries, you missed the sentence. Happens. Always read the problem statement carefully.

#

I thought they;d expect them to just be de-duplicated.

actually happens quite a bit in programming competitions

#

The questions are even worded to be tricky so you need to pay close attention.

#

@gray pulsar Are you able to solve it now?

#

I'd maybe use Counter to do an initial count, then iterate the counter and only use numbers that have a count of 1.

#

But yes, -= is an operator.

#

from collections import Counter
It's a special type of dictionary that counts the elements you give it.

#

You could also just do the same with a loop and normal dictionary.

#

You'd have to count them first to know the amounts.

#

Or a dictionary that you make yourself. Learning how to count elements in a list using a dictionary would be a good exercise on its own.
