What makes you unimpressed? Why do you think that Python clearly wins? Do you think that the additional type safety, namespace safety, and ease of concurrency in Go are worth nothing? Or do you just think that Python has more that outweigh that?
I know that I frequently kick myself in Python when I typo a name somewhere, and everything dies far beyond where I made the mistake because it goes along happily storing something into that typoed variable, and then when I read it later it has the wrong value, and it takes me a while to trace back and find where I made the typo.
This is what linting tools like pyflakes are for. Running it as a prerequisite to running the test suite means that I don't have to run all my tests just to find out that I misspelled a variable name.
