The following functions are available to operate on string and Unicode
objects. They are not available as string methods.
capwords(
s)
Split the argument into words using split(), capitalize
each word using capitalize(), and join the capitalized
words using join(). Note that this replaces runs of
whitespace characters by a single space, and removes leading and
trailing whitespace.
maketrans(
from, to)
Return a translation table suitable for passing to
translate() or regex.compile(), that will map
each character in from into the character at the same position
in to; from and to must have the same length.
Warning:
Don't use strings derived from lowercase
and uppercase as arguments; in some locales, these don't have
the same length. For case conversions, always use
lower() and upper().
