You hardly ever need to do this, its much simpler to just iterate over 
the list items directly:

for number in number_list:

Note that you are overwriting your list with a single value.
You need to do what you did above and use append().

Because you overwrote the list each time. You need to remember to append 
data to lists not replace the list.
