## 4.1.3 String functions

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()`, 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()`.
