Hints:

• Use an accumulator that holds a string value

• For each character in a given string, concatenate that character at the front of that accumulator.

• To control your loop, you may either

  • use an index as a loop control variable, so that string[index] would give access to individual characters, and use the built-in function len() to determine how many times to repeat, OR

  • use the string itself as an iterator, as described in the reading.
