Write a program that inputs student names and writes them to a character file called student_names.txt. This program stops when the input is 'Done'

 

2. How can I write a program that reads the file student_names.txt that is created from exercise #1, and print all of them out, separated by commas.

 

3. How can I write a function that :

    has three input parameters by this order: input_array (a one-dimensional array), slice_start (an integer) , slice_end (an integer),       returns an array by slicing the input array with slice_start and slice_end.

    It has to verify that the input array is a one-dimensional array (not more than one dimension). It has to verify that slice_start <     slice_end. It has to support try /except such that it can catch the error in case the slice_start or slice_end is out of the range.
