update program:
For the verse function to print out the "real" verses to the song, it's going to have to have a way to "remember" the sounds from the previous verses. Use a list to hold the animal sounds. Since the list will need to be "shared" between different calls of the verse function, the list will need to be global. (The other option would be to have the list local to main, but then it would need to be passed as part of each call to verse.) When you declare the global variable, set its value to be an empty list.
The following code fragment gives an example of declaring the variable sounds and assigning an empty list to it.
sounds = []
--->driver function
def main():
# print the first three verses
old_mcdonald.verse('chicken', 'cluck')
old_mcdonald.verse('cow', 'moo')
main()
--->old_mcdonald.py
def verse(animal, sound):
pass
update def verse in old_mcdonald to output

add a second function to old_mcdonald
--->ask the user to input an animal and sound to add to the list
----> If both the animal and the sound pass validation, print out a blank line, then call the verse function, passing the new animal and sound. Following the call to verse, the query_verse function returns True. If either the animal or the sound fails validation, prompt again, up to five times. After five validation failures for the animal or five failures for the sound, the function returns False, indicating that no verse was added to the song.
Explanation / Answer
#user input
def add_verse():
animal = input("Enter an animal: ")
sound = input("Enter that animal's sound: ")
num=0
while(num<5):
num+=1
if query_verse(animal, sound):
verse(animal, sound)
return True
break
return False
#validation
def query_verse(animal, sound):
return (type(animal)==str and type(sound)==str):
#printing verse
def verse(animal, sound):
print animal, sound
