I think `python-shell-send-block' itself is good, but there may be
room for improvement in the test case.

It is better not to use f-strings as much as possible because it
depends on the Python version.

`python-tests-look-at' is basically for moving point.  Since it looks
for the next occurrence of the specified string, it may move the point
to an unexpected location.  For testing, it would be better to use
`looking-at', etc. or compare the point after moving with
`python-tests-look-at' to the expected value.
