Create a new list of the 6th through 13th elements of
lst (eight items in all) and assign it to the variable output.
Section 9.9 Splitting and Joining Strings
Two of the most useful methods on strings involve lists of strings. The
split method 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 character(s) 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 (
wd_lst in this example) is not modified. Also, you can use empty glue (see line 8 above) or multi-character strings (see line 7 above) as glue.
