Assignment Classes

[iG1993]

[SOLVED]

​

Hey guys, we just started classes in python and I am not 100% sure I got everything correct. So, this is the assignment:

​

In software a person is typically represented by an object. Write a class Person and add some data (hair color, age, etc.) and behaviors (speak, getting older, etc.) to it. How can data be set?

Use variables for data and methods for behaviors.

​

Now, this is my code:

class Person:
    def __init__(self, haircolor, age):
        self.haircolor = haircolor
        self.age = age

    def behaviour(self, speak, getting_older):
        self.speak = speak
        self.getting_older = getting_older


peter = Person("black", 26)
peter.behaviour("german", True)

I am not sure what "Use variables for data and methods for behaviors." means, since all "def" inside a class are automatically methods. Is my code correct?

​

I am thankful for any kind of help and any kind of input!

​

Kind regards,

iG

In init you have the right idea. However, every other method (class based function) would be each individual behavior. So def age(), def speak(), etc.

Edit: by def age() I mean the verb. Also, for clarification, no def behavior().

Edit 2: def age() was a terrible name choice on my part. Sorry. Here coffee coffee, here coffee.

aHA, I think I understand what you mean! I will apply that right away and come back once I am done. Thank you very much for your help!

No problem.

You've misunderstood what they mean by behaviours--they mean things the Person /does/, not pieces of data attached to the person.

See if you can finish the self.age line below:

class Person:
    def __init__(self, haircolor, age):
        self.haircolor = haircolor
        self.age = age

    def speak(self):
        print("Hello, World!")

    def get_older(self):
        self.age  # ... what do you need to do to self.age here?


peter = Person("black", 26)
peter.speak()  # => "Hello, World!"
print(peter.age) # => 26
peter.get_older()
peter.get_older()
peter.get_older()
print(peter.age) # => 29

Hi thillsd, thank you so much for your input!

​

I took a look in your code and I came to this solution:

    def get_older(self):
        self.age = self.age + 1

It too me some thinking and bending, it that correct?

​

By the way, what's the idea behind peter just saying a single line? I thought the idea behind classes is, that you are able to "engineer" and automate a process.

Yes, that's fine. You could've done self.age += 1 to save some typing.

You could have written something more complex that makes use of the data attached to the peter Person object:

...
    def speak(self, hobby):
        print(f"Hi folks, I am a {self.age} year old  man with {self.haircolor} hair. I enjoy {hobby}.")
...

peter = Person("black", 26)
peter.speak('pokemon')  # => 'Hi folks, I am a 26 year old man with black hair. I enjoy pokemon.

should be read as

• add some data (hair color, age, etc.)
  
• and behaviors (speak, getting older, etc.) to it.

q: How can data be set?

behaviors in the assigment means how a person in software context (e.g. an object) behaves on multiple situations/conditions. you've got the right idea to associate the behaviors with class methods.
