- ascii_lowercase
- 
  The lowercase letters 'abcdefghijklmnopqrstuvwxyz'.  This
  value is not locale-dependent and will not change.
- ascii_uppercase
-

  value is not locale-dependent and will not change.
- digits
-

- hexdigits
- 
  The string '0123456789abcdefABCDEF'.
- letters
-

  'abcdefghijklmnopqrstuvwxyz'.  Do not change its definition --
  the effect on the routines upper() and
  swapcase() is undefined.  The specific value is
  locale-dependent, and will be updated when
  locale.setlocale() is called.
- octdigits
- 
  The string '01234567'.
- punctuation
