I'm closing this as "Works for me".

rafihassan190041234, if you still think it is a bug in the language, rather than a bug in your code or a mistake in your understanding, you can re-open this with more details. As Zach already commented, you need to give us an explanation of:

- what you expected the code to do;

- why you expected that;

- what it actually did instead;

- your environment (did you run this in an IDE, the plain Python interactive interpreter, from a script, something else?);

- and your operating system.
