I wish you wouldn't describe this as "crash".
The Python interpreter should never crash. That would be a segmentation
fault, and that is considered to be a very serious bug.
But *raising an exception* is another story. Raising exceptions is not a
crash, it is the interpreter working as expected. This statement:
line_number, keyword, expr = "20 END".split(' ', 2)
is SUPPOSED to raise an exception, if it didn't, the interpreter would be
broken. To call that a "crash" is horribly misleading.

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
