def test_whatever():
a = range(10)
b = (10 / x for x in a)
c = list(b)
When I run it with normal Python, this is the exception: Traceback (most recent call last):
File "test_test.py", line 10, in <module>
test_whatever()
File "test_test.py", line 6, in test_whatever
c = list(b)
^^^^^^^
File "test_test.py", line 5, in <genexpr>
b = (10 / x for x in a)
~~~^~~
ZeroDivisionError: division by zero
It's compact and simple to understand. It pinpoints the exact location of the error, and I easily scan the text to find the function call-stack. ___________________________________ test_whatever ___________________________________

It doesn't pinpoint the error, it adds code lines that might be irrelevant, and extra information I don't care about.
