Note efficiencies possible in final exercise!

  • Each string method updates the string it's applied to, so can string them together in series: aString = aString.replace('.', '').replace(',', '')...
  • By casting a list to a set, duplicates are removed, e.g. keys = set(words)
  • By thus removing duplicates, each unique word can be counted in the original text and assigned a dictionary entry.
  • Having the frequency dictionary method available lets us avoid duplicating the tast in freqOf. We can call freqOf to pass us the frequency dictionary, check the word is in it, and if so, return its value. If not, we should return 0, for robustness.
