How do I append a list to a range?

For some reason, I'm struggling to append a range method in a list.

iterating_ranges.py 
my_list = []
for i in my_list:
    range[0,10,1]
    my_list.append([1])

Hi there, Luke Tate! I feel like you're misinterpreting the instructions. The instructions are asking you to iterate over a range. Currently, you're trying to iterate over my_list which is empty so that for loop is never going to run. There are no items to loop over.

my_list = []

for i in range(0, 10):  # loop through the range 0 to 10
    my_list.append(i)  # append the number to the list

You would start by setting the range directly in the for loop. Then for each number in that range, append the number to the previously empty list.

Hope this helps! :sparkles:
