Question

Implement a program that requests from the user a list of words (i.e., strings) and then prints on the screen, one per line, all four-letter strings in the list.

>>> Enter word list: ['stop', 'desktop', 'top', 'post']

stop

post

An acronym is a word formed by taking the first letters of the words in a phrase and then making a word from them. For example, RAM is an acronym for random access memory.

Write a function acronym() that takes a phrase (i.e., a string) as input and then returns the acronym for that phrase.

Note: The acronym should be all uppercase, even if the words in the phrase are not capitalized.

>>> acronym('Random access memory')

'RAM'

>>> acronym('central processing unit')

'CPU'

1. Define a class called Animal that abstracts animals and supports three methods:

• setSpecies(species): Sets the species of the animal object to species.
• setLanguage(language): Sets the language of the animal object to language.
• speak(): Prints a message from the animal as shown below.

The class must support supports a two, one, or no input argument constructor.

Then define Bird as a subclass of Animal and change the behavior of method speak() in class Bird.

>>> snoopy = Animal('dog', 'bark')

>>> snoopy.speak()

I am a dog and I bark.

>>> tweety = Animal('canary')

>>> tweety.speak()

I am a canary and I make sounds.

>>> animal = Animal()

>>> animal.speak()

I am a animal and I make sounds.

>>> daffy = Bird()

>>> daffy.speak()

quack! quack! quack!

Answer 1

strnew =input("Enter word list:")
list = strnew.split (",")
for i in list:
if(len(i)==4):
print(i)
  

Expected output:

def acronym(phrase):
listwrds=phrase.split(' ');
stri="";
for i in listwrds:
stri+=(i.upper())[0];
  
return stri;
  
print(acronym('Random access memory'))
print(acronym('Central processing unit'))

Expected output:

class Animal:

def __init__(self,species="animal",language="make sounds"):
self.__species=species;
self.__language=language;
  
  
  
  
def setSpecies(self,species):
self.__species=species;
  
def setLanguage(self,language):
self.__language=language;
  
def speak(self):
print('I am a '+self.__species+" and I "+self.__language);
  
class Bird(Animal):
  
def speak(self):
print("quack! quack! quack!");
  
snoopy = Animal('dog', 'bark');
snoopy.speak();
tweety = Animal('canary');
tweety.speak();
animal = Animal();
animal.speak();
daffy = Bird();
daffy.speak();

Expected output:
