Write a program, in a file named skip_along.py, which reads a single line of input. Use strip() to remove all leading and trailing whitespace, but leave any internal whitespace intact. First, print out the length of the string, like this: Length (after stripping): 10 Now, use the slice operator (start:end] to slice out substrings from the string. You will then print out the various substrings, separated by commas, on a single line, like this: a, def, klmno, vwxyz You must be able to handle any length string - meaning that you must be able to handle an arbitrary number of substrings. The slices that you keep will follow this pattern: Slice out exactly 1 character from the beginning Then reject the next 2 characters Then slice out the next 3 The reject the next 4 and so on... If the last slice is shorter than you want, print it anyway (see the example above). NOTE: There may be spaces in the middle of your input; treat them exactly like any other character
