Parsons Practice Problems

Please answer the following problems to the best of your ability without any outside help. You can stop working on a problem after you worked on it for about five minutes without solving it.

Problems

Create a class Song with an __init__ method that takes a title as a string and len as a number and initializes these attributes in the current object. Then define the __str__ method to return the title, len. For example, print(s) when s = Song('Respect',150) would print “Respect, 150”.

        class Song:
---
Class Song: #paired
---
  def __init__(self, title, len):
---
  def __init__(title, len): #paired
---
    self.title = title
    self.len = len
---
  def __str__(self):
---
  def __str__(): #paired
---
    return self.title + ", " + str(self.len)
---
    return title + ", " + len #paired
        

Create a class Cat with an __init__ method that takes name as a string and age as a number and initializes these attributes in the current object. Next create the __str__ method that returns “name: name age: age”. For example if c = Cat("Fluffy", 3) then print(c) should print "name: Fluffy age: 3". Then define the make_sound method to return "Meow".

        class Cat:
---
  def __init__(self, name, age):
---
    self.name = name
    self.age = age
---
  def __str__(self):
---
    return f"name: {self.name}, age: {self.age}"
---
    return f"name: {name}, age: {age}" #paired
---
  def make_sound(self):
---
  def make_sound(): #paired
---
    return "Meow"
---
    return self."Meow" #paired
        

Create a class Account with an __init__ method that takes id and balance as numbers. Then create a __str__ method that returns “id, balance”. Next create a deposit method takes amount as a number and adds that to the balance. For example, if a = Account(32, 100) and a.deposit(50) is executed, print(a) should print “32, 150”.

        ---
class Account:
---
    def __init__(self, id, balance):
---
    def __init__(self, id, balance) #paired
---
        self.id = id
        self.balance = balance
---
    def __str__(self):
---
        return f"{self.id}, {self.balance}"
---
        return f"{id}, {balance}" #paired
---
    def deposit(self, amount):
---
        self.balance += amount
---
        self.balance += self.amount #paired
        

Create a class FortuneTeller with an __init__ method that takes a list of fortunes as strings and saves that as an attribute. Then create a tell_fortune method that returns one of the fortunes in the list at random.

        import random
---
class FortuneTeller:
---
    def __init__(self, fortunes):
---
        self.fortunes = fortunes
---
    def tell_fortune(self):
---
    def tell_fortune(): #paired
---
        last = len(self.fortunes) - 1
---
        last = len(self.fortunes) #paired
---
        index = random.randint(0, last)
---
        return self.fortunes[index]
---
        return fortunes[index] #paired
