listOfWords = []

for x in range(len(xString)):
    line = xString[x]
    #print(line)
    listOfWords += line.split()
    x+=1
  
    
#print(listOfWords)
newlist = []
for z in range(len(listOfWords)):
    word = listOfWords[z]
    counter = listOfWords.count(word)
    #print(counter)
    st = word+" occurs "+str(counter)+ " times."
    if not(st in newlist):
        newlist.append(st)
        
    print(st)
    z+=1

print(newlist)
