It prints exactly what I expect.
Try the following:
In python 3, str(x) just wraps x up and puts it in a string. range(x)
generates an iterable range object.
hence str(range(10)) is a string telling you that range(10) is an iterable
range object with certain boundaries.
However, list(iterable) expands the iterable to the full list of possible
values, so str(list(range(10))) is a string representation of the list
containing the values that the iterable range(10) creates.
Note that whether you're looking at a string representation of a value or
the value itself is a lot clearer in the interpreter console where
strings are displayed with quotes.
