John, there's no need to establish every feature in Python that you are **not**
questioning. Please focus on the behaviour that you think is a bug. Pretty much
nothing in your example before the line "So everything here is working as
expected" is necessary. We're experienced Python users, some of us have been
using Python for 20 years or more. We know how int() operates, you don't have
to teach us.
What you have done is confuse the string '2.8' and the float 2.8, which is easy
enough to do as a beginner. The critical error is this line:
int_y = int(2.8) #conver y to an integer 2 and assign to int_y
But that's not converting the variable `y` to an integer, it is converting the
float 2.8 to an integer. 2.8 is already a number, and calling int(2.8) drops
the fractional part leaving 2 as expected.
Had you tried `int_y = int(y)` instead (y being a string) you would have got
the exact error you were expecting.
It takes a little while to completely understand the differences between
strings, ints, floats, literal numbers like 2.8 versus strings like "2.8", but
that will come with some practice.
In future, rather than posting on the bug tracker, please consider asking
questions on one of the many forums where volunteers will answer your questions
and leave the bug tracker for actual bugs.
(Hint: there are many tens of thousands of Python programmers with collectively
thousands of years of experience with the language. As a beginner with only a
few days experience, you are highly unlikely to spot a bug that everyone else
has missed.)
You can try the Python Discussion area:

or the Python-List or Tutor mailing lists:

Good luck!
