Bigger indentation steps *are* more obvious, but on the other
hand, smaller indentation allows you to use more indentation
levels without using up all of your line width. (Using more than
80 chars per line is typically a bad idea.)

In general, I find that you rarely need so many indentation
levels in Python as in e.g. C or C++. I rarely run out of line
width in Python, even though I use 4 space indents and use fairly
long names. Remember that you can freely break lines within pairs
of (), [] and {}, and that adjacent string literals are concatenated.

If you try to squeeze something like...

self.logger.log(log_level, "Blaha bla bla bla bla"
    "at: %s:%i caused a %s with message\n%s\n" %
    (file_name, row, error, error_message))

...into one line, it doesn't matter what indentation depth you use...
