Fixed.

Default Python code comes with an error: two methods of the Compiler class are named "pass1"

See for yourselves:

    def pass1(self, program):
        """Returns an un-optimized AST"""
        tokens = self.tokenize(program)
        pass
        
    def pass1(self, ast):
        """Returns an AST with constant expressions reduced"""
        pass

    def pass3(self, ast):
        """Returns assembly instructions"""
        pass

Voilà, just a small detail to fix.

that's pretty clean!

Generators are fun :)

It's a highly readable code.

Also, it's efficient since it passes the tests in a reasonable time.

Efficiency is always relative. Let's say you have a cog in your system that has a big complexity, but this cog only takes .1% of your runtime, then don't optimize this cog yet and focus on the ones taking way more. Again, Efficiency is always relative.

inefficient

corrected

JS: sample tests are broken

ReferenceError: assert is not defined
    at Context.<anonymous> (test.js:20:9)
    at processImmediate (internal/timers.js:464:21)

You can directly return "class_score < your_points", as this evaluates as a boolean already.

If it's true, you return true. If it's false, you return false. Thus, return it directly:

return class_score < your_points

Agreed, it's solved. Thanks.

the image link is broken (description)

should be ok now. Plz reset the trainer (copy your current code first)

NameError: name 'randint' is not defined

When running the random test cases...

The random.randint import seems missing from the testing file.
