#🔒 python beginner's question

they have a special meaning. init is the initializer to initialze the object

You can think of classes as a way to group data. Classes allows you to store variables and functions in a closed scope.
Dunder methods are special methods for classes which define some lower level methods, one of them is the __init__ also called the constructor method. This always gets fired once during instantiation of a class
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
person1 = Person("baegy", 28)
# The Person("baegy", 28) is called the instantiation of the Person class. And now the variable person1 holds the created instance.
From the above example you can now access those variables from the instantiated class and also you can create endless number of instances of a Person class
print(person1.name, person1.age)
person2 = Person("Jiggly", 18)
print(person2.name, person2.age)
__init__ is usually used to create instance variables of the class

can that print command be placed above the class command?

no python is interpreted not compiled
so it goes line by line
frosty bobcat
everything which is under the current line does not exists (yet)

thank you guys I think I understand the concept
and uhm
this might be another quite dumb question
but for the variable person1, can it also be written as either {} or [] instead of tuples?? why or why not?
reef maple
You can ask you don't need to feel dumb about it

Can you write an example
dull axle
either person1 = Person["baegy", 28] or person1 = Person{"baegy", 28}
reef maple
Yeah that's not a valid syntax
dull axle
why?

you can call the class only with ()
something like Uniform Initialization does not exists
reef maple
{} is a used to define a set or a dictionary, [] is used to define a list or index through a list / tuple or dictionary depending on how it's used, () is used to create a tuple or call a function (depending on how it's used again)
frosty bobcat
you get an new instance when you call the class object and calling in Python is always ()
dull axle
ohh

I once made a brief post on classes and OOP here https://discord.com/channels/267624335836053506/1235883588206202942

Fyi, tuples and () are different ideas. Tuples just sometimes use parenthesis. ,s are actually what you typically need to create a tuple.
!e
x = 1, 2, 3
print(type(x))

```python
x = 1, 2, 3
print(type(x))

x = (1) # doesn't create a tuple
print(type(x))
y = (1,) # or y = 1,

Damn. thank you guys for the input my good sir 🍷. may the rest of your day and ones to follow, be in your favour
