Python Python Collections (2016, retired 2019) Lists Creating lists

python collections list review

not sure what is wrong here keeps saying i need six items in the list but the instructions seem to say something different

number_list = [ 7, 3, 5]
string_list = ["python" , "collection"]
my_list = number_list + string_list

Hi Sam,

The instructions ask for a list with 3 numbers, 2 strings, AND another list with two items in it like this:

my_list = [5, 6, 7, 'cat', 'dog', [2, 0]]

Thus, there are six items total in the final list.
