What is all the info in the info window in Idle?

Python has a rich data-model: https://docs.python.org/3/reference/data...-and-types

Some methods and attributes are created automatically.
For example, you can add the ability of comparison to your class and then all instances are sortable.
But after the creation of the class itself, it gets from object the attributes and methods assigned.
For example, the attribute __name__ holds the name of the class. But you have never created it, it's done automatically.

from functools import total_ordering


# adds additional methods to the class MyFoo
# for comparison
@total_ordering
class MyFoo:
    def __init__(self, value):
        self.value = value

    def __eq__(self, other):
        print("__eq__ called")
        return self.value == other.value

    def __lt__(self, other):
        print("__lt__ called")
        return self.value < other.value

    def __repr__(self):
        return f"MyFoo: {self.value}"

foos = [MyFoo(x) for x in range(10, -1, -1)]

print(foos)
foos.sort()
print(foos)

Output:
[MyFoo: 10, MyFoo: 9, MyFoo: 8, MyFoo: 7, MyFoo: 6, MyFoo: 5, MyFoo: 4, MyFoo: 3, MyFoo: 2, MyFoo: 1, MyFoo: 0]
__lt__ called
__lt__ called
__lt__ called
__lt__ called
__lt__ called
__lt__ called
__lt__ called
__lt__ called
__lt__ called
__lt__ called
[MyFoo: 0, MyFoo: 1, MyFoo: 2, MyFoo: 3, MyFoo: 4, MyFoo: 5, MyFoo: 6, MyFoo: 7, MyFoo: 8, MyFoo: 9, MyFoo: 10]

There is another way with the use of dataclass.
They implement those required methods with the decorator syntax.
The same as a dataclass.

from dataclasses import dataclass


@dataclass(order=True)
class MyFoo2:
    value: int
