Because then you can't really create formatting strings. Instead of
 >>> print("The high temperature at {place:s}, on {date:YYYY-MM-DD}
was {temp:f}" % tempsdict)
 >>> print("{name} scored {score:f}" % locals())
You would have to write
 >>> _tempsdict_copy = dict(tempsdict)
 >>> _tempsdict_copy['place'] = str(_tempsdict_copy['place'])
 >>> _tempsdict_copy['date'] =
 ... datetime.date(_tempsdict_copy['date']).isoformat()
 >>> _tempsdict_copy['temp'] = float(_tempsdict_copy['temp'])
 >>> print("The high temperature at {place}, on {date} was {temp}"
% _tempsdict_copy)
 >>> _f_score = float(score)
 >>> print("{name} scored {score}" % locals())
