I try to use self with the __init__ function in a class, but when I enter the other values e.g. def __init__(self, name): self.name = name /// and when I call the class with a name it says that it need another value because it uses self an another value. It happened when I was using Windows 10, but normally I use Linux.

The file you have attached doesn't seem to be a Python script, it seems to be some sort of Windows batch file or similar.

Please supply an actual Python file. (Hint: remove the "del code.py" line from your batch file.) Also, copy and paste the traceback you receive, as text (not a screenshot).

It may help if you read this for ways to submit good bug reports:

Thank you.

The python file.
It works in Linux (Ubuntu) but not in Windows; at least for me.
The output error is : 
Traceback (most recent call last):
  File "pySelf.py", line 8, in <module>
    print(Person.__init__("Some","One",21,"American"))
TypeError: __init__() missing 1 required positional argument: 'nationality'

The error message is correct. The bug is in your code. Also, the code you tell us that you are running is not the same as the code you are actually running.

You should not call __init__ directly as you do:

    # this is wrong
    Person.__init__("Some","One",21,"American")

Do this instead:

    Person("Some","One",21,"American")


Closing this as it is not a bug in Python, it is a bug in your code.
