It's not really an error-correcting/detecting code.
The idea is that the receiver can infer the clock speed and phase I think.

I'm practising writing Rust by translating some Haskell code and making tests for it
it's surprisingly easy (although quite verbose, because (obviously) it's a different language with different syntax and principles)
maybe one day python will have typing like this too:
class SomeClass(Generic[M]):
def some_method(self, ints: M[int]) -> M[str]: ...
or I may be missing something and it already exists

maybe one day python will have typing like this too:

I think you can theoretically accidentally get generalised models to do such specialised things competently
wouldn't rely on it anyway yet
at some point it may be "easier" for an AI to learn programming from examples and somehow "understand" general programming principles instead of just mimicking the code less intelligently
the problem with generalised is that it tries to generate what people make
people are far far far from perfect and reliable themselves

what's the use of self.__age?
rugged root
So that's an odd way to do it
scenic quiver
i can simply use self.age
rugged root
The double underscores before hand are used for namespace mangling. Usually it means that you're trying to indicate that this should only be used within this class or function or what have you
There's single underscore and double
single is just a convention, it doesn't do anything
Double actually does some namespace mangling to make it harder to do things like animal().__age
scenic quiver
It is actually a double
rugged root
It's probably just to keep it from being easily accessible directly
Normally I'd see this with parameters
One sec, making an example
scenic quiver
One sec, making an example
wow, ok
rugged root
If you're familiar with other languages, you may have seen getters and setters. Specific methods that you would need to call if you wanted to modify an object's attributes (self.name and self.__age in this case)
Python lets you do it directly without the need of those
scenic quiver
yeah
rugged root
However sometimes you want to do some checks before letting a new value being set
And Python has a handy way of doing it via the @property decorator
Writing out the example now, one sec
scenic quiver
okay and also I see py super().__init__(v1,v2,v3)
I am curious to understand the implementation of super()
rugged root
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
@property # The first property is always the getter
def age(self):
print("Getting age")
return self._age
@age.setter
def age(self, value):
print("Setting age")
if value < 0:
print("You can't have someone who is less than 0 years old")
self._age = 0
else:
self._age = value
HOKAY, so
Properties let us control how the we retrieve or set values
scenic quiver
so, what would be the difference when we use self.age instead of self.__age above?
rugged root
Testing something to make sure I'm not going to tell you wrong
Yeah I borked something, one moment
scenic quiver
oops, ok
scenic quiver
I see some error when I am trying to set age to a different value

So for our purposes, anytime someone wants to modify tim's age the normal way tim.age = 4, that would instead call the setter, having it go through the check
willow light
requests? that's soooo 2020, we use httpx now
rugged root
And since we have the self.age = age at the beginning, we tell it to do that check even upon object creation
somber heath
need some help
Unavailable. Sorry.
rugged root
BUT, Python knows that since you're using a property, it knows to actually store the value into tim._age
willow gate
@somber heath ok
rugged root
This keeps it from being modified without the check unintentionally
willow gate
rugged root
However, with it being _age instead of __age, you can still specifically get and set tim._age directly
However if you use tim.__age, it becomes more difficult
willow gate
can anyone help me how to fix this
rugged root
It throws in some complications to make it not that easy
scenic quiver
so, we cannot modify the age when we use double underscores?
rugged root
We can, but it's more effort
It's not as easy as tim.__age
!e Ah, found the example I was looking for:
class ExampleClass:
def __init__(self):
self.var1 = 11
self._baz = 23
self.__foo = 23
exampleObj = ExampleClass()
print(dir(exampleObj))
@rugged root :white_check_mark: Your 3.11 eval job has completed with return code 0.
['_ExampleClass__foo', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_baz', 'var1']
dir just lets us see all the methods and attributes tied to the class/object
We can see _baz and var1 are both there at the end of the list
However, __foo isn't anywhere to be found. Except it is, just made funky
It's now stored as _ExampleClass__foo internally
So we would have to access it by doing exampleObj._ExampleClass__foo
willow light
ethics are in the eye of the beholder
rugged root
It's not impossible to do it, but it makes it difficult to accidentally stumble into it
Nothing in Python is truly hidden
scenic quiver
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
@property # The first property is always the getter
def age(self):
print("Getting age")
return self.age
@age.setter
def age(self, value):
print("Setting age")
if value < 0:
print("You can't have someone who is less than 0 years old")
self.age = 0
else:
self.age = value
p=Person('ram',20)
print(p.age)
print(p.name)
This doesn't run and some error is present
willow light
Nothing in Python is truly hidden
except for a "real" for-loop
rugged root
So after the initialization, Python will store the self.age value as self._age
So you'd need to return self._age, or assign values to self._age
self.age now points to those getter and setter methods under the hood
scenic quiver
so, why my kernel is restarting when I remove the encapsulation?
rugged root
Can you paste the error?
rugged root
Sure, one sec
willow light
"It works on my machine"
scenic quiver
"It works on my machine"
willow light
just use docker podman
rugged root
So those properties modify how python handles assigning to those objects. In this case, since we are setting values by doing self.age, it's running it through the set method over and over and over and over
Which is why we need to assign it to self._age
So the kernel is crashing due to an infinite loop bug
scenic quiver
So the kernel is crashing due to an infinite loop bug
scenic quiver
yeah! Very interesting
rugged root
Oh so you were also asking about super(), right?
scenic quiver
Oh so you were also asking about `super()`, right?
wow! your memory!
rugged root
So I'm going to use the same Person class but strip out all the property stuff, since it's not needed for this example
super() is used when you're dealing with inheritance, which is when you have one class inherit methods and attributes from another one. Usually the one that is being inherited is called the parent class. Let me scratch out a quick example
rugged root
!e
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
class Student(Person):
def __init__(self, name, age, favorite_subject):
super().__init__(name, age)
self.favorite_subject = favorite_subject
tim = Person("Tim", 5)
sally = Student("Sally", 6, "Math")
print(sally.name)
print(sally.favorite_subject)
print()
print(tim.name)
print(tim.favorite_subject)

You do either !e or !eval before your code block

@grand plover :warning: Your 3.11 eval job has completed with return code 0.
[No output]
class Student(Person): indicates that the Student class inherits attributes and methods from the Person class. But in order to properly initialize those attributes we get from Person (age and name) we need some way to call its __init__ function
Enter, the super() function

super()'s job is to let you access the methods of the parent class more easily.
