The following is my effort to understand how to process a
string, letter, by letter:

  The term "process" is a description of the utmost vagueness,
  failing to elucidate your intended actions. Thus, I would
  counsel you to first articulate in the English vernacular the
  objectives you wish to attain, such that any individual could
  compose the code in accordance with said English text.

  The notion of desiring to manipulate a sequence of characters
  in a "character by character" fashion could potentially
  be a vestigial remnant of prior knowledge acquired from other
  programming languages. Perchance, one might adopt an entirely
  disparate approach in Python to accomplish what you truly aspire
  to achieve. Ergo, it is imperative that we comprehend your genuine
  objectives, so as to proffer you the most optimal assistance.
