Process Mad Lib

Question:

Start Quiz:

# Let's put it all together. Write code for the function process_madlib, which takes in 
# a string "madlib" and returns the string "processed", where each instance of
# "NOUN" is replaced with a random noun and each instance of "VERB" is 
# replaced with a random verb. You're free to change what the random functions
# return as verbs or nouns for your own fun, but for submissions keep the code the way it is!

from random import randint

def random_verb():
    random_num = randint(0, 1)
    if random_num == 0:
        return "run"
    else:
        return "kayak"
        
def random_noun():
    random_num = randint(0,1)
    if random_num == 0:
        return "sofa"
    else:
        return "llama"

def word_transformer(word):
    if word == "NOUN":
        return random_noun()
    elif word == "VERB":
        return random_verb()
    else:
        return word[0]

    # you may find the built-in len function useful for this quiz

test_string_1 = "This is a good NOUN to use when you VERB your food"
test_string_2 = "I'm going to VERB to the store and pick up a NOUN or two."
print process_madlib(test_string_1)
print process_madlib(test_string_2)

Solution:

INSTRUCTOR NOTE:

You may not recognize the += operator Sean uses in his answer. += is shorthand for incrementing a variable. The following two lines are equivalent:

x = x + 5
x += 5

In his answer, Sean uses += on strings to build the processed Mad Libs sentence.
