10.25. Strings and Lists¶
Two of the most useful methods on strings involve lists of
breaks a string into a list of words. By
default, any number of whitespace characters is considered a word boundary.
An optional argument called a delimiter can be used to specify which
characters to use as word boundaries. The following example uses the string
ai as the delimiter:
Notice that the delimiter doesn’t appear in the result.
The inverse of the
split method is
join. You choose a
desired separator string, (often called the glue)
and join the list with the glue between each of the elements.
The list that you glue together (
wds in this example) is not modified. Also,
you can use empty glue or multi-character strings as glue.
