Type Error when writing iterable range loop. Bummer: TypeError: list.append() takes exactly one argument (0 given)

I'm wondering what I'm doing wrong to receive this Type Error, could anyone please check this out and let me know what's going on. I thought I placed the my_list.append in the body of the loop where it belongs.

iterating_ranges.py 
my_list = []

for val in range(0, 10, 1):
    my_list.append()

That message "list.append() takes exactly one argument (0 given)" is telling you that the method needs to have an argument, but it's missing.

Also, the instructions said, "To append a value to a list, use the syntax my_list.append(val)" :point_left: note the argument.

Just put val in as the argument and you should pass.
