When I run the program, the output is:
['salem', 'Ali', 'sultan']
I'm not sure which output you think is wrong, or is not doing what you
a) There is no need to import array, you are only using a list.
b) If you try and index into a list using a number greater than the list
length, you will receive an error "IndexError: list index out of range",
hence if you have a list where len(list) is x items you will never be
able to use x! as an index to the list.
c) To refer to a single member of a list, use list[n] where n is the zero
indexed element you wish to refer to.
d) Note point b. l[len(l)!] (or l[Factorials(len(l))]) will always fail.
