In [74]: class Pardon(t

this so?
'From first' is the result of the class definition. 'from second' is the result
of first.second().
And first() doesn't produce any output.
Your problem is probably that you think that the call first() executes all the

because the print statement is not part of the class __init__ code.

you write y = x, then they are not the same variable, but they point to (the
proper Python language is they are bound to) the same object.
Now if you say x.age = 20, then y.age will also be 20 (it's the same object).

There is no Python 3.8.4

only works if that stored hash has been calculated in the same way from the
same key.
On Python 2 (which you shouldn't use) you can leave out the "key = bytes(key,
'ascii')" part.
You can of course make it more sophisticated, for example by
the import system.
Are you running python 3.6?
I tried this on python 3.7 and it worked, but the file is called
_rtmidi.cpython-37m-darwin.so there (37 for python3.7, and the d is missing, I
don't know what that indicates).

he name sys is used in the imported module, that module has to import sys.
Importing it in the calling code doesn't help.
So I would say this is a bug in the module.

In (a) it is composed of the letter o and the accent "́" (Unicode 0x301).
