Let a = 5 (or any other integer). Use that to produce a = ’0..1..2..3..4’ in just one line : So far what I have come up with is a = list(range(5)), however I need it to output in the format of '#,#,#,#'  so I thought oh this is just a string format so I just did a = str(list(range(5))), but this just makes a [#,#,#,#] a string, So im not sure if I am just missing a simple function, or if using range is the correct function.
