# 1) Define a class called Bike that accepts a string and a float as input, and assigns those inputs respectively 
# to two instance variables, color and price. Assign to the variable testOne an instance of Bike whose color is blue 
# and whose price is 89.99. Assign to the variable testTwo an instance of Bike whose color is purple and 
# whose price is 25.0.

# Solution:

class Bike:
    
    def __init__(self, color, price):
        self.color = color
        self.price = price
testOne = Bike('blue', 89.99)
testTwo = Bike('purple', 25.0)



# 2) Create a class called AppleBasket whose constructor accepts two inputs: a string representing a color, and a number 
# representing a quantity of apples. The constructor should initialize two instance variables: apple_color 
# and apple_quantity. Write a class method called increase that increases the quantity by 1 each time it is invoked. 
# You should also write a __str__ method for this class that returns a string of the format: "A basket of 
# [quantity goes here] [color goes here] apples." e.g. "A basket of 4 red apples." or "A basket of 50 blue apples." 
# (Writing some test code that creates instances and assigns values to variables may help you solve this problem!)

# Solution:

class AppleBasket:

    def __init__(self, color, quantity):

        self.apple_color = color
        self.apple_quantity = quantity
    
    def increase(self):
        return self.apple_quantity + 1
    
    def increase(self):
        self.apple_quantity = self.apple_quantity + 1
        
    def __str__(self):
        return "A basket of {} {} apples.".format(self.apple_quantity, self.apple_color)    

basket1 = AppleBasket('red',4)
print(basket1)
basket1.increase()
print(basket1)



# 3) Define a class called BankAccount that accepts the name you want associated with your bank account in a string, 
# and an integer that represents the amount of money in the account. The constructor should initialize two instance 
# variables from those inputs: name and amt. Add a string method so that when you print an instance of BankAccount, 
# you see "Your account, [name goes here], has [start_amt goes here] dollars." Create an instance of this class 
# with "Bob" as the name and 100 as the amount. Save this to the variable t1.

# Solution:

class BankAccount:

    def __init__(self, name, amount):

        self.name = name
        self.start_amt = amount
    
    def __str__(self):
        return "Your account, {}, has {} dollars.".format(self.name, self.start_amt) 

t1 = BankAccount("Bob",100)   
print(t1)
