#Recall in Unit 3 you wrote a function that would count the #number of words in a string using loops. Now that you know #something about string methods, though, let's do that again #using a different approach. # #Write a function called "num_words" that accepts a string #as an argument and returns the number of words in the #string. You can assume all words are separated by a space, #and that the string has at least one word. You do not need #to worry about punctuation.

#function to count number of words in a string

def num_words(str1):

# using split() to count words in string

res = len(str1.split())

return res

test_string = input("Enter string:")

# printing original string

print ("The original string is : " + test_string)

# printing result

print("Number of word in entered string:")

print (num_words(test_string))

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
