python new test framework is required. updated in this fork
Approved!
Very cool how you introduce ast in a simple gentle way. Bravo!
Tests are printing stuff to the console, and misusing
describeanditblocks.fixed in latest fork.
Python 3 should be enabled.
Done.
I'm imagining to exec some
rm -rfin such a calculator, should it be used anywhere ^^OMG, thoughts about fixing that?
It's not fixable.
ast.compilegenerates a code object forevalorexecfrom Python code. That being said, don't worry. The file system isn't writeable (beside/tmp).It's a thing solutions may or may not check, so the question is not whether it's fixable but whether it should be tested. It most likely shouldn't. As for the method, it's possible to traverse the AST and check its nodes against a whitelist. For such an easy problem, however, that would be overkill.
