Return a list of the words in the string, using \var{sep} as the
delimiter string. If \var{maxsplit} is given, at most \var{maxsplit}
splits are done. (thus, the list will have at most \code{\var{maxsplit}+1}
-elements). If \var{maxsplit} is not specified or is zero, then there
+elements). If \var{maxsplit} is not specified, then there
is no limit on the number of splits (all possible splits are made).
Consecutive delimiters are not grouped together and are
deemed to delimit empty strings (for example, \samp{'1,,2'.split(',')}
