def print_expenses(expenses):
    for expense in expenses:
        print(f'Amount: {expense["amount"]}, Category: {expense["category"]}')
    
def total_expenses(expenses):

you are not only writing the lambda, you are writing more than that

3

am i suppose to return it

4

no, you are asked to only write the lambda function

you have written that plus something else that you need to remove

I checked your code. The test wants only the lambda function. But right now, it looks like you’re creating a pair (a tuple) of the lambda and expenses. Just remove the extra part so only the lambda is in the function. Hope that helps. let us know if it works. Good luck!
