This appears to return the right values in my local interpreter, why doesn't it work on Treehouse?

I verified in my local python interpreter that the return value = [{'name': 'large pizza', 'calories': 1500}, {'name': 'burrito', 'calories': 1050}]

However, I'm getting a "Bummer: did you use filter and lambda?" error on Treehouse.

meals = [
    {'name': 'cheeseburger',
     'calories': 750},
    {'name': 'cobb salad',
     'calories': 250},
    {'name': 'large pizza',
     'calories': 1500},
    {'name': 'burrito',
     'calories': 1050},
    {'name': 'stir fry',
     'calories': 625}

high_cal = list(filter(lambda x: x['calories'] > 1000, meals))

Try without list

That did it. Thanks.

I had initially used

high_cal = filter(lambda x: x, [meal for meal in meals if meal['calories'] > 1000])

which also threw the same error.. oh well. Least I was close.
