is printing the result of "a_list.sort()".
Like most Python functions that operate on something (i.e. .sort, which
sorts the list in place), the .sort method returns None. And that is
printed.
But you can use the sorted() function which returns a
sorted copy of the list. So replace your print statement
with
print(sorted(a_list))
gets you the display you want. But does not sort the original.
So it depends on whether you just want to display it, or
actually want to sort it.
Use either:
a_list.sort()
print(a_list)
OR
print(sorted(a_list))
