When called as a function, reverse returns the resulting list, range, or string for convenient use as part of an expression. Cells with zero length strings are considered blank. produce the values ‘a’ and ‘’ (the empty string), respectively.See Testing Flags, for a practical application of findstring. wordList = re.sub("[^\w]", " ", mystr).split() How it works: From the docs : re.sub(pattern, repl, string, count=0, flags=0) Return the string obtained by replacing the leftmost non-overlapping occurrences of pattern in string by the replacement repl. Approach #2 : Using split() and join() First we use split() function to return a list of the words in the string, using sep as the delimiter string.Then, we use join() to concatenate the iterable. If omitted, it defaults to 1 which is the first position in the string. Write a function called 'return_list' that takes a string as a parameter and returns a list of words in the string. function getFrequency (mystring, numofwords) { mystring = mystring.replace (/ [\.,-\/#!$%\^&\*;: {}=\-_`~ ()]/g,""); var words = mystring.split (' '), sortedWords = words.sort (), uniqueWords = [], d = {}, wordcount = 1, result = []; for (var i=0; i"" Evaluates to TRUE if a specified cell contains some data. char *strncpy ( char *str1, char *str2, size_t n) size_t is unassigned short and n is a number.
