How do I join lists with non string items?

The lecture mentions that the .join() method works on lists only if the list has all strings. What if I want to join lists that have numbers too, into a string? How do I do that?

I would simply convert my list so that all elements are strings, and then join. For example:

number_list = [1, 2, 3, 4, 5]
strings_list = [str(x) for x in number_list]
print(",".join(strings_list))
