Python only has about 30 keywords, and the English meaning only helps on some of them. Words like 'lambda' or 'raise' are not immediately intuitive. Translations of function names like raw_input are nice, but you can do that no matter what the base language's keywords look like, and I challenge you to find simple symbols for every built in function, like divmod, help, oct, memoryview, unicode, buffer, delattr.
Yes doing the keywords is one thing, the built-ins another, and harder as well. But given the success logic and mathematics has had with remaining largely symbolic, and the mathematical nature of python, it might be at least an interesting exercise.
