Not to dredge up this debate for the umpteenth time, but the same can be said of unit tests: they are not a proof of correctness, and they often give you a false sense of security.
The Internet has, indeed, conducted this argument thousands of times. My point here is only about the difficulty of reviewing Python code. I find myself sometimes having to hold up a piece of paper to the screen to see if the indentation has been done right, in addition to the aforementioned function-body-reading chores. Of course my opinion is of no concern to people except those who work with me, from whom I refuse to review Python code. It's just not worth my time.
My point is that there are tools and techniques that will solve these problems in ways that are more valuable than the compiler's type system.
If you seriously "refuse to review Python code" because you feel you need to visually check indentation, I think you might want to take a step back and evaluate your methods.
